How Do Rubber Shock Absorbers Work?

The rubber for shocks material is a widely used rubber shock absorber that dampens vibration, muffles sound, and reduces hazards caused by impacts by utilizing the properties of rubber to eliminate mechanical vibrations. This article will briefly introduce rubber for shocks.
Rubber for shocks is a material used to prevent vibration and shock transmission or cushion the strength of vibration and shock. There are three general methods to control vibration, which are to reduce the excitation force of the vibration source, to isolate the vibration source from the structure, and to reduce the structural vibration by moderating the vibration of the vibrating body. Among them, rubber for shocks are mainly used in the latter two methods.
Elastomer type rubber for shocks: Including spring type, extruded type, embossed type, and so on. This type of rubber for shocks mainly utilizes the elastic deformation property of rubber to absorb vibration and shock.
Damping type rubber for shocks: Including leaf spring dampers, hydraulic dampers, pneumatic dampers, and so on. This kind of rubber for shocks mainly use damping materials (such as liquids, gases, etc.) and rubber interaction to consume vibration energy to achieve vibration damping and energy absorption.
Super elastic rubber for shocks: It is a new type of rubber for shocks material. It has micron-level air pore structure, which can absorb vibration and shock through the deformation, damping, and friction of air pores.
The vulcanization system has a great influence on the performance of rubber for shocks, including its stiffness, damping coefficient, heat resistance, and fatigue resistance. Normally, in the network structure of vulcanized rubber, the less sulfur atoms and free sulfur, the stronger the cross-linking, the higher the elastic modulus of the rubber, and the lower the damping coefficient. Damping and dynamic fatigue resistance can be improved if a conventional vulcanization system is used and the degree of crosslinking is appropriately increased. However, this may reduce heat resistance. Therefore, it is important to balance these performance requirements to find the most suitable vulcanization system and crosslinking method to achieve a good balance of rubber for shocks properties.
In the field of construction, rubber for shocks are often used for seismic protection, vibration isolation of building structures, noise control, etc. In the field of transportation, they are often used for roads and other roads. In the field of transportation, they are often used in roads, bridges, railroads, subways, and other projects to reduce the vibration and noise of vehicles and trains. In the field of construction machinery, they are used for vibration and noise reduction of large-scale machinery such as excavators, pile-drivers, and vibratory rollers. In the field of aerospace, they can guarantee the smoothness of aircraft landing and safety during missile transportation.
