Composition and structure of rubber shock absorber

Structure of rubber shock absorber

1. Rubber shock absorber has high elasticity and viscoelasticity. Compared with steel, rubber has great elastic deformation and small elastic modulus;

2. 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 the impact deformation and dynamic deformation;

3. The stress-strain curve is an elliptical lag line, whose area is equal to the vibration energy (damping) which is transformed into heat during each vibration period, which can be adjusted by formula design;

4. The rubber shock absorber is integrated to overcome the disadvantages of high rigidity, high working noise, small weight of rubber spring, poor shape and poor mechanical stability.

5. It has certain friction coefficient, better effect on vibration reduction and noise reduction. In addition, the elastic deformation becomes larger, so it has large bearing capacity, stable operation and short resonance interval.

6. Although the shape of rubber shock absorber is fixed, it is easy to meet the nonlinear requirements because of the large elastic deformation of rubber, and it has better effect on each component.

7. Rubber shape can be freely selected, hardness can be adjusted by formula design, which can meet the requirements of stiffness and strength in different directions.
