Rubber mounts and spring mounts are two different vibration isolators, the difference is also quite large, but its role is to reduce vibration, then in the choice of vibration isolators, many people do not know is to buy rubber mounts or spring mounts. So today we're going to share with you the difference between them:
Characteristics of rubber mounts:
1.Rubber has high elasticity and viscoelasticity; 2. compared with steel material, rubber elastic deformation is large, elastic modulus is 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 elliptic hysteresis line, whose area is equal to the vibration energy (damping) converted into heat in each vibration period, which can be adjusted by formula design; 5. Rubber is incompressible material (Poisson's ratio is 0.5); 6. rubber shape can be freely chosen, hardness can be adjusted by formula design, can meet the requirements of different directions of stiffness and strength; 7. its natural frequency is difficult to achieve below 5HZ; 8. its resistance to environment and high temperature change ability is weak, short life; 9. no sliding part, easy to maintain.
Characteristics of spring mounts:
1.low frequency design, good vibration isolation effect; 2. strong adaptability to the working environment, and can work normally in the environment of -40℃-110℃. The isolation of positive vibration isolation, negative vibration isolation, shock vibration and solid sound transmission is improved. 3. Wide load range and strong adaptability.
Only by understanding the difference between the characteristics of the rubber mounts and the spring mounts can you know which of the two is suitable for the required type of vibration isolators.
