With the rapid development of modern industry, vibration and noise have become serious problems in various fields. It will reduce operation accuracy, affect product quality, shorten product life, make high-precision instruments not work properly, endanger safety, cause early damage to equipment or structures, pollute the environment and affect human health, such as earthquakes and even return Human life and property cause great damage. Therefore, research and mastery of vibration control and noise control technology has become a major issue facing the industrial development of various countries.

The most fundamental and best way to eliminate vibration and noise is to reduce or eliminate the vibration of the vibration source, but in fact it is impossible to completely eliminate the vibration of the vibration source, so other methods of controlling vibration must be adopted. The most extensive and effective method in practical application is to use various shock-absorbing products, especially rubber shock-absorbing products. It can effectively isolate the vibration and excitation source, and can also alleviate the vibration of the vibrating body, so it is widely used in the vibration isolation of various motor vehicles, aircraft, ships and other power machinery and auxiliary equipment and instruments such as fans and water pumps. In recent years, some large buildings and bridges have also used laminated rubber cushions to support the buildings to isolate earthquakes. For the damping of structural vibration and structural noise, special rubber materials are also widely used, called viscoelastic high-damping materials.

The characteristics of rubber are both high elasticity and high viscosity. The elasticity of rubber is produced by the changes in the conformation of its curled molecules. The interaction between rubber molecules will hinder the movement of molecular chains, and exhibit viscous characteristics, resulting in stress. And strain is often in an unbalanced state. The curly long-chain molecular structure of rubber and the weaker secondary forces between the molecules make the rubber material exhibit unique viscoelastic properties, and thus have good shock absorption, sound insulation and cushioning properties. Rubber parts are widely used to isolate vibrations and absorb shocks because of their hysteresis, damping and large reversible deformation.

Rubber shock absorbers are generally called rubber shock absorbers. There are many types of rubber shock absorbers. From the perspective of their vibration force, they can be divided into compression type, shear type, torsional vibration type, impact type and hybrid type. With the development of science and technology, there are more and more types of rubber shock absorbers and more and more uses.
