Rubber shock absorber
Rubber shock absorber main features:
1) The shape can be freely determined, 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 passing the resonance area and attenuating high-frequency vibration and noise;
(3) The elastic modulus is much smaller than that of metal, which can produce large elastic deformation;
(4) No sliding part, easy to maintain;
(5) Small quality, easy installation and disassembly.
Main functions of rubber shock absorber:
Rubber has high elasticity and viscoelasticity;
2) Compared with steel material, rubber elastic deformation is very large, elastic modulus is very small;
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 the impact deformation and dynamic deformation;
4) The stress-strain curve is an elliptical hysteresis line, and its area is equal to the vibration energy (damping) of each vibration period into heat, which can be adjusted by formula design;
5) Rubber is an incompressible material (Poisson's ratio is 0.5)
6) The shape of rubber can be freely selected, and the hardness can be adjusted through the formula design to meet the requirements of stiffness and strength in different directions. As an important shock absorber, rubber shock absorber has been widely used in all kinds of machinery, automobiles, railway locomotives, water transport vehicles, aircraft and other aircraft. It can be said that wherever shock absorption and isolation are needed, rubber shock absorbers are needed
