First, the characteristics of rubber shock absorber:

(1) Rubber has high elasticity and viscoelasticity.

(2) Compared with steel, rubber has large elastic deformation and small elastic modulus.

(3) The impact stiffness of rubber is greater than the dynamic stiffness, and the dynamic stiffness is greater than the static stiffness, which is conducive to reducing impact deformation and dynamic deformation.

(4) The stress or strain curve is an elliptical hysteresis line, and its area is equal to the vibration energy converted into heat in each vibration cycle, which can be adjusted by formula design.

(5) The shape of the rubber can be freely selected, and the hardness can be adjusted by the formula design, which can meet the stiffness and strength requirements of different directions.

Second, the advantages of rubber shock absorbers:

(1) The shape can be adjusted freely, and the hardness can be controlled by adjusting the composition of the rubber formula, which can meet the requirements of stiffness and strength in all directions.

(2) The internal friction is large, the shock absorption effect is good, which is conducive to crossing the resonance area and weakening high-frequency vibration and noise.

(3) The modulus of elasticity is much smaller than that of metal, which can produce large elastic deformation.

(4) No sliding parts, easy to maintain.

(5) Small weight, easy installation and disassembly.

(6) The impact stiffness is higher than the static stiffness and dynamic stiffness, which is conducive to impact deformation.
