Rubber Shock Absorber

Rubber shock absorbers work through elastic deformation and material damping. When the component is compressed, stretched or subjected to shear, the rubber changes shape and absorbs part of the impact or vibration energy. As the rubber returns toward its original shape, internal friction within the elastomer dissipates part of this energy as heat, reducing the amount of vibration transmitted to adjoining components.

This working principle allows rubber buffers, vibration isolators and bonded rubber bushings to cushion impact, reduce noise and limit repeated vibration in automotive and industrial assemblies. Their performance depends on the rubber compound, hardness, component geometry, mounting method and direction of the applied load.

Other important selection factors include:

• Static and dynamic load

• Vibration frequency and displacement

• Available installation space

• Operating temperature

• Exposure to oils, water, chemicals, ozone or weather

• Required compression, movement and service life

A rubber component that is too soft may allow excessive movement, while one that is too hard may transmit more vibration. The product structure and rubber hardness should therefore be selected according to the actual equipment and operating conditions.
