What are the discussions on the damping performance of shock absorber
Since the shock absorber plays a strong role in various mechanical equipment, it will be discussed on its valve performance in many hours, and the following performance characteristics can be obtained from the results of each discussion:
1. The shape can be freely selected, the hardness can be adjusted through the formula design, and can meet the requirements of stiffness and strength in different directions;
2. Is non contractibility data (Poisson's ratio is 0.5);
3. High elasticity and viscoelasticity;
4. Compared with steel material, the elastic deformation is very large and the elastic modulus is very small;
5. The impact stiffness of 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;
6. The stress-strain curve is an elliptical hysteresis line, and its area is equal to the vibration energy (damping) converted into heat in each vibration cycle, which can be adjusted through formula design.
