Because of its superior performance and low cost, it has been widely used in all walks of life and shows a strong product competitiveness. With what advantages does rubber shock absorber have such a large market competitiveness?
Rubber is an ideal wire rope shock absorber material used for vibration reduction and has damping effect on vibration. Rubber is characterized by high elasticity and high viscosity. The interaction between rubber molecules hinders the movement of molecular chains and exhibits viscous characteristics, resulting in the unbalance of stress and strain.

Rubber has great linear flexibility, can be stretched to break without losing its elasticity, and can withstand alternating stress without fatigue. Rubber is the same as water. It can not be compressed at all. After compression, only elastic deformation occurs, but its volume remains unchanged. The compressive strength of rubber is much greater than the tensile strength. The elongation of rubber is usually about six times longer than the contraction interval. When rubber is stretched or compressed, its natural oscillation frequency is not the same.

The long-chain molecular structure of rubber and the weak secondary force between the molecules make the rubber vibration absorbing material used have the same viscoelastic function, so they have excellent shock absorption, sound insulation and cushioning functions. Rubber components are widely used to block vibration and absorb shock, that is, because of their hysteresis, damping and reversible large deformation characteristics.

In addition, rubber also has hysteresis and internal conflict characteristics. They usually use the loss factor to show that the greater the loss factor, the more significant the rubber damping and heat generation, and the more significant the shock absorption effect. In summary, rubber also has excellent shock absorption.

Practical Use and Selection of Rubber Isolator(2023年)

hoanisolator — 2023-01-20T15:26:57+0900

https://www.hoanisolator.com/news/practical-use-and-selection-of-rubber-isolator.html
The shock isolation effect of different rubber isolators is different, so the vibration amplitude of the machine will be different. Different amplitudes have different effects on the operating efficiency of the machine, resulting in different fluctuation range of machine operation, and then the fluctuation range of finished products produced by the machine will be different. Therefore, rubber vibration isolator is one of the important factors affecting the vibration of the whole machine.
Anti vibration mount selection
Generally, the selection of isolator should consider the following: excellent elastic performance and low stiffness; High bearing capacity, high strength and proper damping; The durability is good, the performance is stable, and it does not change the performance due to the external temperature, humidity and other conditions. Strong acid, alkali and oil erosion ability; Easy access to materials, stable prices; Convenient for processing, maintenance and replacement; Non-toxic, non-radioactive; It has flame retardant properties. Rubber isolators are more cost-effective than other isolators.
Rubber isolator is the simplest vibration isolation component made of rubber material, and it is also a common vibration isolation device in engineering. It can be divided into compression type, shear type and compression shear type. The rubber isolator is generally composed of a restraint surface and a free surface. The restraint surface is usually connected with metal. The free surface refers to the side that deforms when it is loaded vertically on the restraint surface. The vibration isolation parameters of the rubber isolator are not only related to the composition of the rubber material used, but also related to the factors such as the shape of the structure, the mode of force and so on. Compared with the spring, the rubber isolator has the following characteristics: rubber is easy to shape, it can be firmly bonded together with metal, and can be made into various arbitrarily complex shapes. Rubber has internal friction and critical damping is large, so it rarely has the strong resonance of a steel spring, or the special resonance of a spiral spring.
In addition, rubber vibration isolator is usually made by combining rubber with metal. The sound resistance of metal and rubber is relatively high, which can effectively play the role of sound insulation. The elastic coefficient of the rubber isolator can be changed in a wide range by changing the rubber composition and structure to meet the needs of design and use. The rubber isolator is not suitable for the low natural frequencies, and the static compression capacity cannot be too large. Therefore, it is not suitable for systems with low interference frequency and equipment with large weight. It is more suitable for vibration isolation of small and medium-sized equipment. The commonly used frequency range is 5 ~ 15Hz. The performance of rubber isolator is greatly affected by temperature, and its performance is not good at high temperature; the elastic coefficient will change when it is used at low temperature, so it must be used in accordance with the actual situation.

Overview of Vibration Isolation and Elimination Methods(2023年)

hoanisolator — 2023-01-20T15:23:56+0900

https://www.hoanisolator.com/overview-of-vibration-isolation-and-elimination-methods.html
According to whether the purpose of isolator is to isolate the response or the source, the industrial vibration control methods can be divided into passive isolation and active isolation.
(1) Passive vibration isolation. The purpose of reducing the vibration caused by the foundation motion is to isolate the response. If the isolator is designed according to the isolation requirements of the isolator, instead of analyzing the excitation signal of the vibration source to reduce the intensity of the vibration source, this isolation method is called passive isolation. For example, the wire vibration isolator used under the precise instrument on the ship is designed according to the vibration isolation requirements of the instrument. This kind of vibration isolation selection method is passive vibration isolation by weakening the influence of vibration source on vibration isolation object.

(2) Active vibration isolation. The purpose of reducing the vibration caused by the disturbance of a vibrating object is to isolate the source of vibration. On the contrary, if the isolator is actually based on the analysis of the excitation signal of the source to reduce the intensity of the source, rather than on the isolation requirements of the isolator, it is called active isolation. For example, vibration isolators are installed on the engine base to offset the impact of engine vibration on the base. This kind of vibration isolation method is active vibration isolation by restraining the influence of vibration source on vibration isolation object.

The classification of vibration reduction methods is based on the different mechanical properties of the interaction force between the damper and the damper. There are mainly the following types:
(1) Damping. The single damping force is used to dissipate the energy of the vibration system and the damping force is used to eliminate the vibration. Common vibration isolation dampers are mainly high damper materials, which have been widely used in engineering.

(2) Vibration attenuation by dynamic tuning. By using the inertia force and restoring force of the mass of the damper, the method of vibration elimination is called dynamic tuning vibration elimination. It is mainly used for vibration reduction of simple harmonic vibration system with constant frequency.

(3) Damping dynamic vibration attenuation. Damping dynamic vibration reduction is achieved by inertia force and motion damping force of the active mass of the damper.

(4) Shock attenuation. Using the moving mass of the damper and the incomplete elastic collision between the dampers to exchange momentum and dissipated kinetic energy, the vibration can be eliminated.

(5) Gyro vibration attenuation. The gyroscope vibration is eliminated by the gyroscope force generated by the high-speed rotating gyroscope rotor.

(6) Active vibration control by vibration isolation techniques. Active control is similar to active vibration isolation, which requires external equipment to provide energy.

Overview of Cabinet Vibration Damping System(2023年)

hoanisolator — 2023-01-20T15:19:54+0900

https://www.hoanisolator.com/news/overview-of-cabinet-vibration-damping-system.html
It is well known that the mechanical forces received by electronic equipment come in many forms, among which vibration and impact are the most harmful, causing about 80 percent of faults. The main device resonates under the action of an excitation frequency, exceeding the limit of the equipment. Car-mounted electronic equipment is generally installed in the cabinet, mainly depending on the damping buffer of cabinet vibration damping system. The installation of the shock absorber has been standardized for the cabinet above 1.2 meters high. That is, four shock absorbers are installed at the bottom of the equipment and two shock absorbers are installed at the upper back.

Anti-resonance design and decoupling design are two major problems to be solved in the vibration reduction system of the overhead cabinet. To prevent damage to equipment by excessive resonance transfer rate, in practice, we should first choose wire vibration absorber with low vibration transmission rate and low natural frequency to suppress the resonance of cabinet. The gravity installation is adopted for the cabinet shock absorber to avoid coupling vibration. In practice, however, this installation is difficult to achieve. In order to make the cabinet anti-vibration system have good anti-vibration effect, the vertical rigidity of the anti-vibration system is required to be close to zero, and its horizontal rigidity should match the horizontal rigidity of the bottom shock absorber.

Currently, there are four types of commonly used shock absorbers for automobile cabinets: type E shock absorber, wire rope vibration isolator, non-harmonic peak shock absorber and composite damping shock absorber.

The advantages and disadvantages are as follows:
type E shock absorber: The static deformation is small and the installation is convenient. It is more suitable for the internal installation of the square cabin and box, but the natural frequency is high (anti-resonance is required).
wire rope vibration isolator: The rigidity has a soft nonlinear characteristic, low transmission rate, and can adapt to various stress states. Wire rope vibration dampers are mainly suitable for wall-mounted installation.
non-resonant peak shock absorber: It has good vibration reduction and shock isolation effect, long life. But the load must be within 20% of the rated load of the shock absorber, otherwise, the effect will be worse.
composite damping shock absorber: It has good impact resistance. But it required installation space.

The angular acceleration of the cabinet of onboard electronic equipment is large, and the stiffness of the shock absorber at the bottom is weak for the horizontal direction.

The following principles should be followed when selecting the back shock absorber:
The vertical rigidity of the back frame damper should be approximately 0, so as to keep the vertical direction decoupling of the cabinet;
The horizontal rigidity should be symmetrical about the static equilibrium position of the cabinet to eliminate coupling resonance;
The vibration damper of the back frame should match the stiffness and damping characteristics of the bottom damper.

General measures to reduce vibration and buffer include:
Install the shock absorber. The damping and buffering of electronic products mainly depend on the installation of shock absorbers. At present, the standardized rubber shock absorber and metal spring shock absorber are applied in the electronics industry.
Enhance the vibration and impact resistance of products and components.

hoanisolator — 2023-01-20T15:07:04+0900

https://www.hoanisolator.com/news/how-to-choose-industrial-vibration-dampers.html
Why Choose Industrial vibration dampers for machines
At present, the use of industrial vibration dampener is very common in industrial production. There are already a lot of industrial manufacturers that use industrial vibration dampers for production. The industrial vibration dampers can play a great role, when used, they can well reduce the vibration sense of the equipment and the noise in the environment. Of course, when choosing, we need to have a careful understanding of the product, and we need to make a comprehensive selection.

industrial vibration dampener / industrial vibration dampers are selected according to the environment and the use of equipment. Industrial wire vibration isolator should be selected first to understand the environment in which they are used. At the same time, the selection of industrial vibration dampers should require that the quality, installation and after-sale service are guaranteed, so it is important for merchants to find them.

Industrial vibration dampers are screened layer by layer when they are used, because the use in industry is very important for safety, environment and production, so careful selection is needed when using them.

The Greatest Role of Industrial Vibration Dampers in Industrial Production
In the industrial production, wire rope vibration dampers can reduce the noise and alleviate the sense of vibration in the environment. If it can be used with other shock absorbing equipment, it can also well control the source, which is very important for industrial production. Of course, industrial vibration dampers are designed for use in industrial parks. If the seismic source can be found in the process of use, the vibration damper can be used to block the seismic source, which can play a very good role.

Generally, the damping of industrial vibration damper is very good, which can effectively reduce noise, reduce vibration and improve environmental purity. Industrial vibration damper plays an important role in industrial production and is indispensable auxiliary equipment in industrial production.

Damping Spring Isolator for Generator Set(2023年)

hoanisolator — 2023-01-20T15:01:22+0900

https://www.hoanisolator.com/news/damping-spring-isolator-for-generator-set.html
Diesel generators are very common as standby power supply for factories, large property and large communities. Its tremendous vibration and roaring field are impressive. Nowadays, the vibration and noise of diesel generating sets have already attracted the attention of generator manufacturers, generator installation companies and generator users. Generally, rubber shock absorbers are marked when generating units leave the factory. When some equipments leave the factory, the damper spring isolator is installed at the request of the owner. This paper introduces the special damper spring isolator and rubber shock absorber for vibration reduction of generating units.

Rubber vibration isolators for generators commonly used in large generating units include rubber gaskets and metal rubber dampers. Rubber gasket is believed to be able to understand that it does not need to be fixed, directly under the base of Dafa generating unit can play a certain role in shock absorption; Metal rubber shock absorber is generally installed between the two bases under the generating unit. At present, most generating units are equipped with rubber shock absorbers when they leave the factory.

However, its shock absorption effect is quite different. We will analyze the reason for you. The price of fake and inferior products is much lower than that of regular shock absorbers. In addition, the lack of knowledge of shock absorbers has resulted in the pure shape of shock absorbers purchased by many generator manufacturers, but the performance of shock absorbers is very general. Generally rubber shock absorbers need a good compression curve, rated downpressure should be 5-8MM; the material should be chloroprene, natural rubber as the best, and recycled rubber should not be used.

Damping spring isolator has better vibration reduction effect than rubber isolator. It has longer service life, lower natural frequency and better vibration reduction performance. The special damper spring isolators for generating units have the following characteristics: excellent surface antirust treatment, suitable structural strength, adjustable height and stable spring performance.

The JMZ-T Series vibration sandwich mounts can also be used in the very narrow spaces to meet the mountable environmental requirements. This new type friction damper is the very selection for the limits of the space under some special situations.

Impact Curve of JMZ-T Series vibration damping sandwich mounts:
An earthquake is caused by the motion of the ground which causes the forced vibration of a building that is still at rest on the ground, resulting in internal forces, deformation and displacement in the structure. Vibrational isolation is an isolated earthquake, To isolate or dissipate vibration energy by setting a control mechanism at the base or at a certain location of buildings and structures to avoid or reduce the transmission of vibration energy to the upper structure, reduced the vibration response of the structure, so that only minor motion and deformation of the building can be realized during the earthquake to ensure the safety of buildings. In isolation technology, foundation isolation technology is a hot new technology in the world. The base isolation technology is widely used, it is especially suitable for medium-and low-rise brick-concrete buildings and reinforced concrete buildings.

What is the basic vibration isolation technology
Traditional vibration isolation structure mainly utilizes plastic deformation and energy dissipation of the main structure to dissipate vibration energy after yielding, therefore, the performance requirements of these regions are particularly important. Once these areas have problems due to certain factors, it will affect the vibration resistance of the structure seriously, even produce serious damage. And the foundation isolation is to set a layer of isolation with sufficient reliability between the superstructure of the building and the top of the foundation to separate the superstructure from the foundation, and blocks the propagation of vibration waves to the superstructure, so that the vibration energy of the input structure is absorbed by the energy dissipation elements of the isolation layer, therefore, it will reduce the vibration response of the superstructure greatly, so that ensure the safety of the building.

The basic principle of base isolation technology
According to the experiment, if the period of the structure is prolonged and a large damping is given, it will greatly reduce the acceleration response on the structure. At the same time, large displacements to the structure can be provided by an isolation layer between the bottom of the upper structure and the top of the foundation. In this way, the superstructure will move close to translation during the earthquake, so the safety degree of the superstructure is greatly improved, which is the principle of base isolation. If a damping device is introduced into the structure, the displacement response of the structure can be reduced, and the corresponding acceleration response can also be reduced.

https://www.hoanisolator.com/wire-rope-isolator/multi-application-wire-rope-isolator/

Among all of wire rope isolator manufacturers, Hoan is proud to release multi-application wire rope isolators. The wire rope vibration isolator overcomes the defect of passive wire rope vibration dampers that damping is not adjustable, but because the structure of the mechanical system is complex, so the multi-application wire rope isolator price is expensive, it is mainly used for vibration isolation of some advanced cars or heavy cars.
In recent years, the continuous development of intelligent materials provides a research foundation for the development of new intelligent wire rope vibration isolator. The intelligent vibration isolator has great application potential in the field of automobile vibration isolation technology because of large stiffness and damping range, small energy consumption, the simple structure of the mechanical system, low manufacturing cost, high reliability, real-time response and good controllability.

Application of Wire Rope Isolators in the Field of Automotive Vibration Isolation Technology
The automobile is a complex vibration system composed of multiple systems. The vibration of automobile or part would be generated when it is driving due to road roughness, speed and direction changes, the imbalance between wheels, engine and transmission system, gear impact and other external and internal excitation. The vibration of the automobile makes its power not fully exerted, affects the stability and smoothness of the automobile, causes the function of the automobile equipment to fail or even be damaged, and shortens the life of the automobile. With the continuous development of automobile to high speed and the heavy load, the demand for vibration isolation of automobiles is getting higher and higher, so it is very important to properly use wire rope isolators to solve the problem of automobile vibration.

This kind of wire rope isolator are used widely in the field of RC car, camera drone, UAV camera, video, military vehicles, highway transportation, marine, shipbuilding, navy, energy, photographic equipment, aerial equipment, communication apparatus, electronic sensing devices, mobile electronic devices, cameras or any other needed working conditions.

Classification of Wire Rope Isolators
The wire rope shock absorber can be divided into a passive wire rope vibration isolator and active wire vibration isolator according to whether it needs energy or not. Passive wire rope isolators have been widely used because of its simple structure, easy implementation, good economy, and reliability, without external energy. But because the damping is not adjustable, the isolation ability is limited. The active wire rope isolators feel the vibration of the isolation object through the sensor and passes the output signal to the controller, then the actuator sends out action instructions and uses the external energy to change the stiffness and damping of the isolator to achieve the purpose of isolating the vibration.

Hoan is one of the leading wire rope isolator manufacturers in China, with 13-year production experience, we are sure to provide you with quality vibration isolation products. Welcome to consult for wire rope isolator price.

Among all of wire rope isolator manufacturers, Hoan is proud to release multi-application wire rope isolators. The wire rope isolators overcome the defect of passive wire rope vibration dampers that damping is not adjustable, but because the structure of the mechanical system is complex, so the multi-application wire rope isolator price is expensive, it is mainly used for vibration isolation of some advanced cars or heavy cars.

In recent years, the continuous development of intelligent materials provides a research foundation for the development of new intelligent vibration isolators. The intelligent vibration isolator has great application potential in the field of automobile vibration isolation technology because of large stiffness and damping range, small energy consumption, the simple structure of the mechanical system, low manufacturing cost, high reliability, real-time response and good controllability.

This kind of wire rope isolator is used widely in the field of RC car, camera drone, UAV camera, video, military vehicles, highway transportation, marine, shipbuilding, navy, energy, photographic equipment, aerial equipment, communication apparatus, electronic sensing devices, mobile electronic devices, cameras or any other needed working conditions.

Classification of Wire Rope Isolators
The wire rope shock absorber can be divided into a passive wire rope vibration isolator mounts and active wire rope isolator according to whether it needs energy or not. Passive wire rope isolator has been widely used because of its simple structure, easy implementation, good economy, and reliability, without external energy. But because the damping is not adjustable, the isolation ability is limited. The active wire rope isolator feels the vibration of the isolation object through the sensor and passes the output signal to the controller, then the actuator sends out action instructions and uses the external energy to change the stiffness and damping of the isolator to achieve the purpose of isolating the vibration.

With the rapid development of modern industrial engineering, the various manufacturing machine, transportation machine are all developing to high speed, high efficiency, high precision, and automation. However, with the increase of equipment's power and speed, the intensity of the vibration source in engineering practice is increasing constantly, the harm is also obvious because of vibration and noise. Vibration does the great harm to operators, precision instruments, machinery equipment and architectural structure, at the same time, vibration and the noise is also bad for people's living condition and physical and mental health. Therefore, harm from vibration and noise is drawing more and more attention from researchers from various countries.

Vibration and noise are harmful in most cases, vibration hazards are regarded as one of the seven environmental hazards. The hazards of vibration and noise can be divided into the following aspects:

1. Harm to human bodies
When vibration is over certain strength, it will do harm to human bodies. People will have insomnia, lumbago, backache, fatigue, impotence, headache, dizzy, drowsy, gastro-intestinal, low appetite and weak attention id they are under the environment of large vibration and noise for a long time, it is also easy to make mistakes and technical error, what's worse, it will make people's senses blunt and cause physical illness.

2. Harm to structures of buildings
Vibration brings unsafe factors to buildings when vibration is acting on buildings, that is to say, mechanical energy is acting on buildings, it will create deformation. Vibration makes bigger deformation and setting of the ground. When vibration frequency and building structure frequency is the same or similar, the harm will be more serious, it even makes buildings fall down. Vibration will cause uneven sedimentation and damage plant and equipment if the basic geological condition of equipment is bad.

3. Produce noise and pollute the environment
At present, machinery equipment and power is larger and larger and its variety is more and more diversified, after the vibration from machinery equipment is transferred to basics, floors, walls and other structure, vibration will transfer to other room by elastic waves and create vibration between neighboring air, so the vibration of objects will be spread to everywhere in the form of sound wave, that is what we called noise. Ferroconcrete and metal are the good material for isolating air noise, but it makes no differences for solid state noise, sometimes a pump can break the peace of the whole building.

4. Influence the precision of precise instrument and equipment
Vibration breaks the accuracy, reliability and sensitivity. If the instruments and apparatus are near the strong vibration source, vibration will have the different influence on them. Influence on the normal operation of instruments and influence on the accuracy of the scale of apparatus reduces the precision of measurement, what's worse, it will make instruments out of order, especially for electric instruments.

Therefore, how to decrease the harm of vibration and noise efficiently is a very important issue for the industrial development all over the world, vibration control is the most direct way to decrease the harm of vibration and noise in engineering practice, so the research of vibration control is necessary for controlling vibration and noise.

The rubber vibration isolation mounts are the newly designed model, providing superior attenuation of medium to high-frequency vibration and noise emanating which is designed especially for the military use. Comparing with the wire rope isolators, this model is small and tiny, which has no worrying about the space limits. And its metal outer shell is good for outdoor use, and prevent the damage to the rubber elastic element.

From the 1970s, the technology of rubber vibration isolation mounts is applied to the project construction of bridge, road, and railroad. Contact deformation, friction, and damping of vibrations occurring in temporary fastenings and permanent joints have the essential influence on dynamical properties of machines and devices. Many people find rubber isolation mounts suppliers and seek more reliable anti-vibration solutions.

Applications of Anti Vibration Mount
The anti vibration mount can also be used in the very narrow spaces to meet the mountable environmental requirements. This new type of friction damper is the very selection for the limits of the space under some special situations.

The anti-vibration mount can be specially used in many precision equipment and system in a helicopter, motor, embedded electronics, automotive, alternator, air compressor, mechanical equipment, construction, home appliance, aviation (aerospace anti vibration mounts), office facilities, test machines etc. It can load heavy duty machines (heavy duty anti vibration rubber mounts), it's good to reduce shock and noise.

Advantsges of Rubber Vibration Isolation Mounts
Rubber anti vibration mounts are a new type of vibration isolator, they are made of metal wire through several processes like spirally forming, drawing out, winding blank and mould pressing, its interior structure is space network structure by interlacing of metal wire, at the same time, it has elasticity and damping capacity which is similar to high molecular rubber material. When it is out of shape because of loading, fine wire hook chain structure will have slippage, friction, extrusion and elastic deformation, it will cause vibration reduction and cushion and dissipate a lot of vibrational energy by dry-friction damping.

Metal rubber belongs to discontinuous body pore material, so with the increase of the times of vibration, its interior metal wire will have the partial fracture and accumulated damage, which is different from continuous body pore material. Metal rubber is made of spiral wire, it not only has good elasticity like rubber material but also corrosion resistance, radio resistance, high and low-temperature resistance and age resistance like metal material. Therefore, the metal rubber vibration isolators is suitable for the special environmental condition. Metal rubber can also be made in all shapes and its relative density, weight, rigidity can be adjusted, it also has high dynamic static strength.

What Factors should be Considered when Choosing a Vibration Isolator?(2022年)

hoanisolator — 2022-02-17T15:00:34+0900

https://www.hoanisolator.com/what-factors-should-be-considered-when-choosing-a-vibration-isolator.html

Information about the correct selection, installation requirements, and use of vibration isolators can be obtained from the manufacturer. Some basic things to consider include:

1.The size of the equipment whose vibration is isolated by vibration isolator
The load range of some vibration isolation materials may limit the choice of wire rope isolator type.

2.The nature of the isolated dynamic excitation by vibration isolator
Dynamic force is defined as periodic, random or transient (impact), and its amplitude, direction and frequency are also important factors that determine the type of vibration isolation system. For example, for isolating machines that generate 5 Hz dynamic force, elastic isolators will not be the right choice, but air springs may be a better choice.

3.Vibration allowed by vibration isolator
This will define the required vibration isolation efficiency. Based on this standard, several options may be removed from the consideration list.

4.Working environment of vibration isolator
Extreme temperatures and corrosive environments will remove some isolator types from the consideration list. For example, for applications that require operation at very high temperatures in a corrosive environment, a special stainless steel spiral cable vibration isolator may be a better choice than a standard metal spiral spring. Certain environments either reduce the physical integrity of the vibration isolator or change its operating characteristics.

5. Movement restrictions on vibration isolator
The flexibility of the vibration isolation spring may cause very large movements of the isolated equipment, especially when the rotation speed of the equipment passes the natural frequency of the spring during the shutdown process, a braking device or other safety stops may be necessary. During normal operation, the safety stop should not short-circuit the vibration isolation system.

6.Weight and center of gravity of the equipment whose vibration is isolated by vibration isolator
It is recommended that the distance between the vibration isolation plane and the center of gravity of the vibration isolation equipment should be equal to or less than one-third of the distance between the vibration isolators.

The Difference Between Rubber Shock Isolators and Rubber Vibration Dampening Mounts(2022年)

hoanisolator — 2022-02-17T15:00:08+0900

https://www.hoanisolator.com/rubber-shock-isolators-and-rubber-vibration-dampening-mounts.html

The shock absorber industry has developed a lot of shock absorber components. There are more and more rubber shock isolators on the market, and many consumers are picking on them. In the eyes of the layman, it is true that he does not know how to choose, or what the difference is between the names of one word.

For example, the vibration and shock absorbing mounts rubber shock absorber vibration isolator mounts and the rubber shock isolators, generally many people do not understand the difference between them, how to choose the use of methods and occasions.

Rubber shock isolators and cable shock absorber mounts seem to play the same role, but in fact there are differences, one is to isolate vibration, the other is to reduce vibration, although the role played is similar, but the final effect is often different. In certain environments, tech products vibration isolators must be used. For example, for all kinds of mechanical equipment on land and ship, vibro isolator can be used for horizontal disturbing mechanical equipment.

Overview of Vibration Isolation and Elimination Methods(2022年)

hoanisolator — 2022-02-17T14:59:33+0900

https://www.hoanisolator.com/overview-of-vibration-isolation-and-elimination-methods.html

According to whether the purpose of isolator is to isolate the response or the source, the vibration mountings & controls methods can be divided into passive isolation and active isolation.
(1) Active and passive vibration isolation. The purpose of reducing the vibration caused by the foundation motion is to isolate the response. If the isolator is designed according to the isolation requirements of the isolator, instead of analyzing the excitation signal of the vibration source to reduce the intensity of the vibration source, this isolation method is called passive isolation. For example, the wire vibration isolator used under the precise instrument on the ship is designed according to the vibration isolation requirements of the instrument. This kind of vibration isolation selection method is passive vibration isolation by weakening the influence of vibration source on vibration isolation object.

(2) Active vibration isolation. The purpose of reducing the vibration caused by the disturbance of a vibrating object is to isolate the source of vibration. On the contrary, if the isolator is actually based on the analysis of the excitation signal of the source to reduce the intensity of the source, rather than on the isolation requirements of the isolator, it is called active isolation. For example, vibration isolation dampers are installed on the engine base to offset the impact of engine vibration on the base. This kind of vibration isolation method is active vibration isolation by restraining the influence of vibration source on vibration isolation object.

The classification of anti vibration methods is based on the different mechanical properties of the interaction force between the damper and the damper. There are mainly the following types:
(1) Damping. The single damping force is used to dissipate the energy of the vibration system and the damping force is used to eliminate the vibration. Common vibration isolation dampers are mainly high damper materials, which have been widely used in engineering.

(3) Damping dynamic vibration attenuation. Damping dynamic vibration reduction is achieved by inertia force and motion damping force of the active mass of the damper.

(5) Gyro vibration attenuation. The gyroscope vibration is eliminated by the gyroscope force generated by the high-speed rotating gyroscope rotor.

(6) Active vibration control by vibration isolation techniques. Active control is similar to active vibration isolation, which requires external equipment to provide energy.

Overview of the Vibration Isolation of the Elevator(2022年)

hoanisolator — 2022-02-17T14:59:05+0900

https://www.hoanisolator.com/overview-of-the-vibration-isolation-of-the-elevator.html

With the rapid development of China's economy, the elevator market is extremely prosperous, with an annual demand of more than 40,000 units, making it the most active market in the world.

An elevator is a stationary lifting device that serves a defined floor. It has a car that runs between at least two columns of rigid rails that are perpendicular or inclined at an angle of less than 15°. The size and structure of the car should be such that passengers can access or load cargo.

Operation Principle of Elevator
The traction elevator is connected to the car through one end of the traction wire rope, and the opposite end is connected to the counterweight balancing device. The gravity of the car and the counterweight causes the traction wire rope to be pressed in the rope groove of the traction sheave. When the motor rotates, the friction between the traction wire rope and the rope groove of the traction sheave drives the wire rope to make the car and the counterweight move relative to each other, so that the car runs up and down along the guide rail in the hoistway. Because China's elevators are greatly affected by Japanese products, people's requirements for elevator comfort are getting higher and higher.

Application of Vibration Isolator in Elevator
How to improve the comfort of elevator operation has become an important issue for all elevator manufacturers.

Many elevator manufacturers randomly select cable isolators without according to the wire rope isolator selection guide. In fact, the shock isolator plays a very important role in improving the comfort of the elevator.

The vibration isolator generally has three kinds of rubber vibration isolation pads of the traction machine base, vibration isolation springs or rubber vibration isolation pads at the bottom of the car, and wire rope vibration isolators at the top of the car. The vibration isolation pad of the traction machine base has different quality and vibration isolation effect, which directly affects the comfort of the elevator. Especially when the elevator goes up to the top 2 to 4 floor to start and stop, the problem will be outstanding.

The quality of the vibration isolator at the bottom of the car will be directly related to the smooth running of the elevator. If the modulus of elasticity is large and the characteristics are too hard, vibration isolation will not be achieved. It will generate high-frequency vibration, and the human body will feel the feeling of hemp. In severe cases, it will cause high-frequency vibration of the car and generate relatively loud noise. On the contrary, low frequency oscillations will occur, causing the body to sink. Therefore, vibration isolator selection must be rational. The vibration isolation of the wire rope is the same as that of the vibration isolator at the bottom of the car. According to the height of the floor, a wire rope with a reasonable elastic coefficient must be selected.

Under the condition of full load, if the amount of expansion and contraction meets the requirements, a good vibration isolation effect is achieved. In addition, in the high-rise elevator, since the wire rope is long and the degree of tightness is poor, it is easy to cause the wire rope to oscillate at high speed, and the vibration of the car is caused by mutual impact. An effective method is to add a wire rope isolator at the end of the wire rope to effectively absorb the vibration wave of the wire rope and prevent reflection from forming a beat phenomenon.

The Future Development of Vibration Isolators
The development of vibration isolators has received more and more attention. Being a mainstream isolators are resistance-adjustable isolators, especially electronically controlled vibration isolators. The sensor can detect the running state, and the calculating unit calculates the optimal damping force, so that the damping force adjusting mechanism on the vibration isolator automatically works, and the damping force of the damper is adjusted by changing the size of the orifice. The smooth ride comfort and handling stability of the elevator are the main indicators to measure the damping performance, but these two aspects are mutually exclusive performance requirements. Therefore, it is difficult to achieve the ideal optimal point between maneuverability and comfort. Therefore, the ideal vibration isolation damping in the future can meet both the smoothness requirement and the steering stability requirements.

In the future, excellent vibration isolators should have the following characteristics: high-precision column plugs, oil seals with good airtightness, high-quality damping oil, and air chamber design filled with high-pressure gas. Of course, it is best to be adjustable.

All in all, as new technologies, new processes, and new materials are applied to the elevator industry, people's attention and requirements for the comfort of elevator operation are constantly increasing, so it is necessary to pay attention to the ap

Difference between Vibration Absorber and Vibration Isolator Principle

Vibration isolator and vibration absorber:
The rubber shear vibration isolator is composed of metal and rubber, which can resist oil and aging. The upper screw hole is connected with the vibration isolation pedestal of the equipment worker, and the installation of a metal rubber composite plate is connected and fixed with the foundation bolt. (it can also press the round composite plate of the base) it is easy to install and replace.

Plate rubber vibration isolator is made of iron plate and synthetic rubber by molding and vulcanizing. The utility model has the advantages of simple structure, convenient installation, replacement, wide load range and low natural frequency. Suitable for working temperature - 5 ℃ - 50 ℃, damping ratio ≥ 0. 078.

Rubber vibration isolator can be used for vibration isolation of power equipment such as pipeline pump, vertical and horizontal water pump, fan, water chiller, heat pump, generator, etc.

The spring vibration absorber can bear a large range of load, from several thousand grams to dozens of tons, and the static compression is also large, the maximum can reach tens of millimeters.

Its advantages can be summarized as follows:
1. The natural vibration frequency is low. Therefore, the low-frequency vibration isolation is better than other vibration isolation devices;
2. The utility model has a long service life, can resist the erosion of oil and water, and is not affected by the temperature;
3. The mechanical properties are stable, the design calculation method is mature, and the calculation value is close to the test value;
4. It is easy to process and produce, and its characteristics change little;
5. Low price.

Damping vibration absorber has the double advantages of wide selection, large load range, low natural frequency and large damping. It has strong adaptability. It has significant effect on active vibration isolation, passive vibration isolation and impact vibration isolation. It is an ideal shock absorber to reduce vibration hazards and protect the environment. It is also an ideal shock absorber to eliminate the inherent resonance amplitude surge phenomenon of spring.

The disadvantage of the spring vibration absorber is that the damping ratio is small, and the amplification factor is large when it vibrates, so it is easy to transmit high-frequency vibration, and the stability of the horizontal direction is poor. Therefore, if there is a requirement for this, the damping spring vibration absorber can be selected. This product is a new product designed for the defect of the spring vibration absorber.

Spring vibration absorber is used for various water chillers, cooling towers, floor fans or floor air conditioning boxes.

The Difference between Stainless Steel Splint and Aluminium Splint of Wire Rope Isolator(2021年12月11日)

hoanisolator — 2021-12-08T12:51:31+0900

https://www.hoanisolator.com/difference-between-stainless-steel-splint-and-aluminium-splint.html

Wire rope isolators have been widely used in the isolation and buffering of airborne, vehicle-borne, shipborne and other electronic, mechanical equipment, computers and instruments, the safety protection of missile satellite delivery, navigation and launch systems, and the isolation and buffering of machinery, electronic equipment and facilities in harsh environments such as high and low temperature and chemical pollution. At present, the steel wire rope vibration isolator splint in the market is mainly divided into stainless steel material and aluminum material. The two materials have their own performance advantages, and their main characteristics are as follows:

Properties of stainless steel:
1. Chemical properties: the best material for resisting electrochemical corrosion
2. Physical properties: heat resistance
3. Mechanical properties: good strength and hardness
4. Machinability: Stainless steel can be used to manufacture many products due to its good plasticity.

Classification Characteristics and Functions of Vibration Isolators(2021年12月10日)

https://www.hoanisolator.com/classification-and-functions-of-vibration-isolators.html

The wire rope isolator is an elastic body made of stainless steel wire ropes and fixed by stainless steel splints. It can effectively avoid strong resonance and impact, and achieve the purpose of aerospace vibration isolator, shock resistance and buffering.

Vibration isolator is an elastic element connecting equipment and foundation, which is used to reduce and eliminate the vibration force transmitted from equipment to foundation and the vibration transmitted from foundation to equipment. It is used for main engine, auxiliary machine, various power machinery and instruments to avoid vibration, reduce vibration, noise and prevent impact.

For example, spring vibration isolator is the most commonly used steel vibration isolator. There are spiral, dish, ring and plate forms. Its advantages are large static compression, low natural frequency and good low frequency vibration isolation performance. In addition, it can withstand the erosion of oil and water. Temperature changes do not affect the performance, aging and creep.

Metal rubber vibration isolator has great advantages because of its original material. Metal rubber is a simulation product of natural rubber. Metal rubber components are made of wire and do not contain any natural rubber, but they have the same elasticity and porosity as natural rubber. They are especially suitable for solving high and low temperature, large temperature difference, high pressure, high vacuum, strong radiation, severe vibration and corrosion. The lower damper reduces the vibration. Its interior is reticulate, similar to the macromolecular structure of natural rubber. Under the action of alternating stress and strain, a large amount of vibration energy is dissipated, and the damping in the resonance region increases significantly, which can effectively suppress the resonance peak value, and the damping in the isolation region decreases rapidly. Therefore, it has excellent damping characteristics, with a damping ratio of 0.2 to 0.3.

Rubber isolators are widely used, because they are made of rubber, so they can be used in shear, compression or shear pressure, rarely in tension. Its advantage is that it can be made into various shapes and different stiffness. Its internal damping effect is larger than that of steel spring, and it can be separated from the excitation frequency of about 10 Hz.

The air cushion isolator is usually inflated by rubber parts. When the frequency of vibration is very low, its vibration isolation effect is better than that of steel spring. The natural frequency can be as low as 0.1-5 Hz. It has high damping in resonance and low damping in high frequency. The disadvantage is: expensive, limited load, and need to be checked regularly. Air cushion isolator can be divided into two kinds: one-way and two-way.

Equipment vibration isolators can be used in pumps. For example, the design elements of vibration isolation of pumping units should be calculated according to vibration isolator specification, speed, system quality, installation location, load value, frequency ratio and other factors. The frequency ratio of vibration isolation of pumping unit should be 2-5, which should be high in places with high requirements for vibration isolation.

Horizontal pumps generally use rubber vibration isolation cushion, when installed on the floor, multi-layer series rubber vibration isolation cushion or damper spring vibration isolator should be used. Rubber vibration isolator is suitable for vertical pumps. The supporting points of vibration isolation elements should be even, but not less than 4. The type, specifications and performance of the vibration isolation elements of each supporting point of a pump unit should be the same.

Application of Wire Rope Isolator for Vibration Damping in Vibration and Shock Isolation(2021年12月09日)

hoanisolator — 2021-12-08T12:50:14+0900

https://www.hoanisolator.com/application-of-wire-rope-isolator-in-vibration-and-shock-isolation.html

With the deepening of isolation research and the development of isolation technology, nonlinear isolators suitable for various occasions have emerged. Laminated springs for the automotive industry are widely used in China. The principle is to use the dry friction between the steel plates to reduce the vibration and impact caused by the unevenness of the road. There are metal conical coil springs for the civil industry, as well as air springs.

During the entire deformation process of the wire rope shock mounts, sliding friction will occur between each wire rope, which consumes a large amount of energy and has a high equivalent damping ratio. Moreover, the wire rope anti vibration mounts exhibit nonlinear softening characteristics in a large deformation range, the stiffness decreases as the deformation increases, and the vibration isolation rate increases. Therefore, the good broadband isolation performance of the wire rope vibration dampers is especially suitable for the application of vibration and shock environment isolation.

The wire rope shock mounts have only been developed in the last 30 years.

Advantages of Wire Rope Anti Vibration Mounts
① Nonlinear soft characteristics;
② Multi-directional isolation, high damping ratio;
③ Corrosion, high and low temperature resistance;
④ Compact structure and light weight.

Classification of Wire Rope Anti Vibration Mounts
At present, the common wire rope anti vibration mounts have several types of spiral, arch and ring. But in either case, they are made of stainless steel wire rope wound or bent.

Their common advantage is the three-way protection of the equipment, reliable operation in high temperature and harsh environments, wide load range, unlimited storage period and service life. In terms of impact resistance, The wire rope shock mount can achieve maximum impact attenuation in a minimum space, and its vertical allowable deformation can reach 40~60% of the height of the vibration isolator.

In foreign countries, they are used in the transportation of some equipment to replace the impact-resistant packaging of raw plastics and rubber. Rocket and missile transport vehicles also use it. In terms of ships, it passed the tests of light impact machines, heavy impact machines and floating impact platforms to meet the requirements of MIL-S-901 and MIL-STD-167. The compact wire rope isolator has excellent durability and fatigue. A vibration isolator with a diameter of 2.4 mm has been tested for up to 150 hours and seven million tests at 13 Hz and ±1.5 mm amplitude. The result is safe and sound.

For a 1.5 mm wire rope isolator damping with a 1.5 mm diameter, a sweep vibration test up to 10KHZ was performed, and the vibration isolation effect was 95%. This proves that the wire rope isolator for vibration damping can isolate small amplitude and structural noise. Wire rope anti vibration mounts are widely used in vibration and shock isolation of instruments, instruments, control boxes, etc., and some original rubber vibration isolators have been replaced by wire rope shock mounts.

What is the basic vibration isolation technology
Traditional vibration isolation structure mainly utilizes plastic deformation and energy dissipation of the main structure to dissipate vibration energy after yielding，therefore, the performance requirements of these regions are particularly important. Once these areas have problems due to certain factors, it will affect the vibration resistance of the structure seriously, even produce serious damage. And the foundation isolation is to set a layer of isolation with sufficient reliability between the superstructure of the building and the top of the foundation to separate the superstructure from the foundation, and blocks the propagation of vibration waves to the superstructure, so that the vibration energy of the input structure is absorbed by the energy dissipation elements of the isolation layer, therefore, it will reduce the vibration response of the superstructure greatly, so that ensure the safety of the building.

JMZ-T1 Industrial Anti Vibration Isolator Dampers & Mounts(2021年)

It has good performances such as anti-humidity, anti-salt fog, high and low-temperature resistance, mold resistance and long service life.

The composition of the foundation isolation system
Foundation isolation system is generally composed of isolators, dampers, ground micro-vibration and response control devices, and so on. The main function of the isolator is: on the one hand the weight of the building on the vertical side, on the other hand, in the horizontal direction, providing a certain horizontal stiffness, in order to avoid the excellent period of ground motion and reduce the seismic response of buildings, the base period of buildings can be extended, and the ability of deformation and self-reset can be provided. The main function of the damper is to absorb or dissipate seismic energy to restrain structure produces large displacement response, at the same time help the isolator reset quickly at the end of the earthquake. The main functions of the ground micro vibration and wind response control device are: increase the initial stiffness of the isolation system to keep buildings stable under wind or mild earthquakes.

Structural requirements of the isolation layer
1. When the isolation layer of a multistory masonry building is located at the top of the basement, Seismic action and seismic checking calculation of walls and columns under the isolation layer should adopt the vertical force, horizontal force and moment at the base of the isolated bearing under rare earthquake.

2. Isolation bearings and dampers should be installed in areas that are accessible to maintainers. In isolated buildings, isolated story members have the advantage that they can be replaced. The displacement of dampers which are independent of shock isolators is more convenient; The isolation support bears the weight of the building, which is not as easy to replace as the damper. Therefore, local jacks should be installed to replace or reinforce the isolator in accessible areas.

3. Connectors between isolation support and superstructure and foundation structure should be able to transfer the maximum level of support shear.

4. Exposed embedded parts should have reliable anti-rust measures. Anchorage reinforcement of embedded parts should be firmly connected with steel plates; Anchorage length of anchorage steel bar should be more than 20 times the diameter of anchorage steel bar, and should not be less than 250mm.

5. In the event of a massive earthquake, to prevent the deformation of the building from causing a collision. So, the water squared upward should be guaranteed to have a clearance spacing of 1.5-2.1 times the seismic deformation of the superstructure.

6. In order to ensure the overall coordination of the isolation layer, the beam-slab system with enough stiffness in the plane should be installed at the top of the isolation layer. When adopting integral reinforced concrete plates, cast-in-place should be used in the longitudinal and transverse beams on the upper side of the support to transfer vertical load to the longitudinal beam system and to coordinate the distribution of transverse shear force on each isolation support, at the same time, to increase the in-plane stiffness of beam and slab, it is necessary to enlarge the cross-sectional dimension and reinforcement of the beam, when the superstructure is masonry, its construction shall conform to the requirements of reinforced concrete joist for bottom frame brick building. Cast-in-place area thickness should not be less than 50mm, the steel mesh with the diameter of 6mm-8 mm and spacing of 150mm-250mm should be arranged in both directions.

Analysis of Advantages and Disadvantages of Rubber Shock Absorber(2021年)

hoanisolator — 2021-11-17T18:46:25+0900

https://www.hoanisolator.com/advantages-and-disadvantages-of-rubber-shock-absorber.html

The wire rope isolator is an elastic body made of stainless steel wire ropes and fixed by stainless steel splints. It can effectively avoid strong resonance and impact, and achieve the purpose of electrical panel vibration isolators, shock resistance and buffering.

Advantages of Shock Absorber:
1. It can be made into products of various shapes and different hardness, with outstanding elasticity and sufficient strength;
2. It can make the natural frequency of the vibration isolation system lower and have higher damping.
3. No matter in tension, compression, shearing and changing force, the deformation is relatively large.
Comparing with metal spring shock absorber, wire rope shock absorber can determine shape freely and control hardness by adjusting rubber composition. It can satisfy the requirement of stiffness and strength in all directions.
4. The internal conflict is large and the shock absorption effect is good, which is conducive to skipping the resonance zone and attenuating the high frequency oscillation and noise.
5. The modulus of elasticity is much smaller than that of metal, and large elastic deformation can occur.
6. It is easy to maintain without sliding.
7. Small quality, convenient installation and disassembly.
8. Impact stiffness is higher than static stiffness and dynamic stiffness, which is beneficial to impact deformation.

Disadvantages of Shock Absorber:
1. It is difficult to achieve the natural frequency below 5Hz.
2. Its ability to resist environmental pollution and temperature change is weak and its life is short.

Rubber shock absorber is widely used because of its durable high elasticity, excellent functions of vibration isolation, shock isolation and sound insulation; convenient appearance and restriction, it can freely choose shape and scale to satisfy the requirements of stiffness and strength; rubber vibration absorber has certain damping function, can absorb mechanical energy, especially the absorption of high-frequency oscillation energy; because of rubber materials and gold. Because of the strong bonding between surfaces, it is not only easy to manufacture devices, but also able to reduce stiffness by using multi-layer superposition, changing its frequency scale and low cost.

Of course, like rubber shock absorbers, rubber vibration isolation pads also have their disadvantages, such as vulnerability to temperature, oil, ozone, sunlight and chemical solvents corrosion, formation of functional changes and aging, easy to relax, so the life is generally about 8 years, but no more than 10 years of corrosion.

The function of rubber vibration isolation pad is not only related to the shape and formula of rubber pad, but also to the hardness of rubber. It has high hardness, high stiffness, high load-bearing capacity, low hardness, low stiffness and low load-bearing capacity. The hardness of some rubber cushions can be divided into 40, 60 and 90 degrees. It is important to pay attention to when selecting them.

Brief Introduction of Research on Nonlinear Performance of Wire Rope Vibration Dampers(2021年05月11日)

hoanisolator — 2021-05-06T16:58:35+0900

https://www.hoanisolator.com/wire-rope-isolator/multi-application-wire-rope-isolator/

Wire rope vibration damper has been widely used because of its simple structure, easy installation, light weight and excellent vibration isolation performance. Such products can be found in machinery, transportation, aviation, ships and construction. As early as the early 1980s, some people studied wire rope vibration dampers, and developed a number of wire rope vibration dampers with non-linear characteristics through a large number of experiments. With the development of technology, the research and Simulation of the non-linear performance of wire rope vibration dampers are also deepening and developing.

Because of the large deformation of the wire rope vibration damper, the slip between the wires produces frictional resistance, thus forming a restoring force form of hysteretic loops. It includes not only strong geometric nonlinearity, but also considerable physical nonlinearity. It contains not only large friction resistance, but also viscous damping. It is a very complex mechanical system. In order to simplify the calculation, according to the shape of hysteresis loop and Dunhada's ideal friction model, a bilinear hysteresis model is established, which is also the most typical model in mathematics. At that time, it was believed that the natural frequency of wire rope vibration damper decreased with the increase of amplitude, and it had some characteristics of non-linear soft spring. In addition, some methods such as first-order non-linear differential equation model and trace method model are proposed.

Brief Analysis of Mechanical Impedance of Wire Rope Vibration Dampers(2021年05月10日)

hoanisolator — 2021-05-06T16:58:01+0900

https://www.hoanisolator.com/wire-rope-isolator/multi-application-wire-rope-isolator/

As a new type of non-linear vibration isolator, wire rope vibration damper has a wide application prospect in vibration and noise control. However, at present, the theoretical analysis and experimental study of wire rope vibration dampers are still mainly focused on stiffness and damping, while the analysis of mechanical impedance is rare.

As mechanical impedance and parameter identification technology is an effective means for modern analysis and research of mechanical and structural dynamics problems, and a new technology combining theoretical analysis with experimental research, it is more convenient and simple to adopt mechanical impedance technology than other methods in the design and evaluation of system vibration isolation and sound isolation. At the same time, the dynamic stiffness of wire rope vibration damper can only reflect the performance at low frequency, but can not be applied at high frequency. The noise of the structure is proportional to the product of the velocity of each point and its corresponding area, so the noise curve and the velocity admittance curve are basically the same. Therefore, it is very important to apply mechanical impedance method to the analysis of vibration isolation and sound isolation.

Generally speaking, when the wire rope vibration damper is used as a single-degree-of-freedom system for analysis, its mechanical model is a parallel structure of damper and spring. Among them, the damping part can be regarded as structural damping, and its loss factor is more than 0.2. The specific value depends on the length, strand number, diameter and winding mode of the wire rope. The elastic part has a non-linear property, and its rigidity coefficient is related to the magnitude of motion.

Difference and concept between shock absorber and vibration isolator
A shock absorber is the main means to prevent vibration hazards in engineering. The shock absorber can be divided into active shock absorber and passive shock absorber. The active vibration damper is designed to eliminate the vibration source or reduce the energy or frequency of the vibration source. It is widely used in precision instruments, aerospace equipment, large steam turbine generator units and high-speed rotating machinery, but it is expensive and less used in common construction machinery. Passive shock absorbers include vibration isolators and absorbers. The isolator can be divided into active isolator and passive isolator.
In order to prevent or limit the harm and influence caused by vibration, various measures are adopted in modern engineering

1. Reduce or eliminate the vibration source (active shock absorber)
This is a positive fundamental measure. If the vibration is caused by the eccentricity of the rotating parts, the unbalanced centrifugal inertia force can be reduced by improving the dynamic balance accuracy. For reciprocating machinery such as air compressor, attention should also be paid to the balance of inertia force.
2. Keep away from a vibration source (passive vibration isolator)
This is a negative protective measure. For example, precision instruments or equipment should be as far away as possible from factories or workshops with large power machinery, pressure processing machinery and vibration machinery, as well as railways and highways with busy transportation.
3. Improve the anti-vibration ability of the machine itself (active shock absorber)
The commonly used index to measure the anti-vibration ability of the machine structure is the dynamic stiffness, which is equal to the dynamic force required by the unit amplitude of the machine structure. The larger the dynamic stiffness, the smaller the vibration of the machine structure under the dynamic force.
4. Avoid resonance area
Change the natural frequency of the system (active damper) or the working speed of the machine (passive damper) as much as possible according to the actual situation, so that the machine does not work in the resonance area.
5. Increase damping appropriately (damping and vibration absorption)
Damping absorbs the vibration energy of the system and makes the amplitude of the free vibration attenuate rapidly. It can restrain the amplitude of the forced vibration, especially in the resonance region.
6. Dynamic vibration absorption (passive vibration absorption)
For measuring or monitoring instruments on some equipment, the method of installing dynamic vibration absorber under the instrument can stabilize the pointer of the instrument and improve the measurement accuracy.
7. Take vibration isolator measures
Using elastic vibration isolator to isolate the vibrating machine (vibration source) from the foundation, so as to reduce the vibration source to affect the surrounding equipment through the foundation, which is the active vibration isolator; or isolating the precision equipment to be protected from the impact of the surrounding vibration source, which is the passive vibration isolator.

According to the materials, it can be divided into natural rubber and synthetic rubber. Natural rubber is superior in physical and mechanical properties, while synthetic rubber is outstanding in some special properties, such as oil resistance, aging resistance, acid and alkali resistance, ozone resistance and high-temperature resistance.

Rubber isolation mounting feet can be divided into plate type, pressure type and shear type. As far as the vibration isolation effect is concerned, the pressure type is better than the plate type, and the shear-type is better than the pressure type.

There are 40, 60 and 80 kinds of rubber isolation mounting feet according to the shore hardness. The static compression amount of rubber isolation mounting feet with different shore hardness is different under the same load condition.

Rubber shock isolator is rubber-based isolator. It is characterized by low bearing capacity, large rigidity and creeps effect. The damping coefficient is 0.15-0.30. It can be made into various forms so as to freely select the rigidity in three directions. It is mainly used for machine vibration isolation. When the load is large, it is made of pressure bearing type; when the load is small, it is made of shear type.
1. Rubber shock isolators can be divided into compression type, shear-type and compression shear type
(1) compressed rubber stock isolators
Generally, this type of vibration isolator can bear a large load, and it is often used in places with a large load or small space size of installation position. The compression type can also be made into a variety of shapes and structures to meet the requirements of various working conditions, such as circular, square and other shapes, external convex or internal concave, and the middle can also have openings or interlayer, etc.
(2) shear type rubber stock isolators
This kind of vibration isolator are mostly used in the situation of low stiffness in the main direction of action, or in the mechanical vibration isolation with a light load and low speed, and their vibration isolation effect is good, but their stability is slightly poor. Shape and structure can also be diversified.
(3) rubber shop isolators
This kind of isolator is a kind of compression rubber shock isolators placed obliquely. Its structural shape is changeable, and its internal and external shape is different. The stress angle is mainly pressure and shear. It is often used in the situation of high requirements for vibration isolation and stability. Sometimes, it needs three-way equal stiffness vibration isolators, which are mostly solved by combining the structure shape.
2. The application and characteristics of rubber stock isolators
Rubber shock isolators are vibration isolators with metal parts as the framework, rubber as the elastic element and vulcanized and bonded together, so they are sometimes called metal rubber shock isolators, which are the most widely used vibration isolators at present, mainly used for the vibration isolation of general mechanical equipment (fans, compressors, water pumps, air conditioning units, etc.) and various engines; automobile, train, urban rail transit. Traffic equipment such as communication, aircraft and ships can not be separated from rubber shock isolators; Some stamping and forging equipment also use rubber shock isolators to isolate vibration.
3. The main features of rubber stock isolators are as follows:
(1) the shape and size can be freely selected, the manufacturing is relatively convenient, and the hardness change is easy to adjust. The rigidity in three mutually perpendicular directions can be arbitrarily selected according to the needs, and the rubber shape, internal and external structures can be changed to adapt to the needs of greatly changing the rigidity and strength.

(2) rubber material has proper damping, which can absorb vibration energy, especially for high-frequency vibration energy. It is obvious that the absorption is above 30Hz. When the vibration machine equipped with rubber shock isolators passes through the resonance area, even when it is close to the resonance area, it can be used safely without excessive vibration, so there is no need to configure another damper.

(3) rubber shock isolators can significantly reduce the high-frequency structural noise (generally, it can reduce the structural noise in the frequency band of 100-3200hz to about 20dB), which is very beneficial to the control of noise.

(4) the effect of impact resistance is also good.

A Brief Introduction to Wire Rope Isolators Damping(2021年05月06日)

hoanisolator — 2021-05-06T16:55:13+0900

Wire rope isolators damping (damping) refers to the characteristic that the vibration amplitude of any vibration system decreases gradually due to the external action or the inherent reason of the system itself, as well as the quantitative characterization of this characteristic. In electricity, it means response time.

In order to provide the resistance of movement and reduce the energy of movement, the device is called wire rope isolators damper. Wire rope isolators damping is used to absorb energy and reduce vibration. In aerospace, aviation, military, gun, automobile and other industries, various wire rope isolators damping (or shock absorbers) have been used to reduce vibration and energy dissipation.

In physics, the decrease of the energy of the system -- the vibration of wire rope isolators damping is not always caused by "resistance". In terms of mechanical vibration, one is the heat generated by friction resistance, which makes the mechanical energy of the system reduce and convert into internal energy. This kind of wire rope isolators damping is called friction wire rope isolators damping; the other is the vibration of the surrounding particle caused by the system, which makes the energy of the whole system radiates out to all sides gradually and becomes the energy of waves. This kind of wire rope isolators damping is called radiation wire rope isolators damping.

Wire rope isolators damping is a kind of action that can block the relative motion of objects and convert the motion energy into heat energy or other energy that can be dissipated.

The main functions of wire rope isolators damping are as follows:
(1) wire rope isolators damping is helpful to reduce the resonance amplitude of mechanical structure, so as to avoid the mechanical damage caused by the vibration stress reaching the limit;
(2) wire rope isolators damping is helpful for the mechanical system to recover to a stable state soon after being impacted instantaneously;
(3) wire rope isolator damping is helpful to reduce the sound radiation caused by mechanical vibration and mechanical noise. The noise of many mechanical components, such as the shell of transportation tools and saw blades, is mainly caused by vibration. The use of wire rope isolators damping can effectively suppress the resonance and reduce the noise;
(4) it can improve the processing accuracy, measurement accuracy and working accuracy of all kinds of machine tools and instruments. All kinds of machines, especially precision machine tools, need high seismic resistance and dynamic stability when they work in a dynamic environment. The dynamic performance can be greatly improved by wire rope isolators damping;
(5) wire rope isolators damping is helpful to reduce the ability to transmit vibration. In the design of vibration isolation structure of a mechanical system, the effect of vibration isolation and damping can be significantly improved by using wire rope isolators damping technology reasonably.

Practical Use and Selection of Rubber Isolator(2020年10月01日)

hoanisolator — 2020-09-25T17:00:00+0900

The shock isolation effect of different rubber isolators is different, so the vibration amplitude of the machine will be different. Different amplitudes have different effects on the operating efficiency of the machine, resulting in different fluctuation range of machine operation, and then the fluctuation range of finished products produced by the machine will be different. Therefore, rubber vibration isolator is one of the important factors affecting the vibration of the whole machine.
Generally, the selection of isolator should consider the following: excellent elastic performance and low stiffness; High bearing capacity, high strength and proper damping; The durability is good, the performance is stable, and it does not change the performance due to the external temperature, humidity and other conditions. Strong acid, alkali and oil erosion ability; Easy access to materials, stable prices; Convenient for processing, maintenance and replacement; Non-toxic, non-radioactive; It has flame retardant properties. Rubber isolators are more cost-effective than other isolators.
Rubber isolator is the simplest vibration isolation component made of rubber material, and it is also a common vibration isolation device in engineering. It can be divided into compression type, shear type and compression shear type. The rubber isolator is generally composed of a restraint surface and a free surface. The restraint surface is usually connected with metal. The free surface refers to the side that deforms when it is loaded vertically on the restraint surface. The vibration isolation parameters of the rubber isolator are not only related to the composition of the rubber material used, but also related to the factors such as the shape of the structure, the mode of force and so on. Compared with the spring, the rubber isolator has the following characteristics: rubber is easy to shape, it can be firmly bonded together with metal, and can be made into various arbitrarily complex shapes. Rubber has internal friction and critical damping is large, so it rarely has the strong resonance of a steel spring, or the special resonance of a spiral spring.
In addition, rubber vibration isolator is usually made by combining rubber with metal. The sound resistance of metal and rubber is relatively high, which can effectively play the role of sound insulation. The elastic coefficient of the rubber isolator can be changed in a wide range by changing the rubber composition and structure to meet the needs of design and use. The rubber isolator is not suitable for the low natural frequencies, and the static compression capacity cannot be too large. Therefore, it is not suitable for systems with low interference frequency and equipment with large weight. It is more suitable for vibration isolation of small and medium-sized equipment. The commonly used frequency range is 5 ~ 15Hz. The performance of rubber isolator is greatly affected by temperature, and its performance is not good at high temperature; the elastic coefficient will change when it is used at low temperature, so it must be used in accordance with the actual situation.
