Difference of rubber vibration isolator and rubber shock absorber?

Oct 23, 2018

       Rubber vibration isolator and rubber shock absorber seem to be the same, but there are still differences, one is to block vibration, the other is to reduce vibration, although the effect is similar, but the final effect is often not same. In some specific environments, it is necessary to use vibration isolators, such as various types of land and marine machinery. It is good for vibration isolators on horizontally disturbed mechanical equipment.

 What are the characteristics of the rubber isolator?

1. Low natural frequency;

2. The damping ratio is suitable;

3. The lateral stiffness is higher than the vertical stiffness;

4, use a variety of installation forms such as flat, inverted and side hanging.

     In fact, when the rubber isolator is used flat, the lateral stability is good. When subjected to a relatively large vibration shock, it can absorb vibration and automatically limit the protection. At the same time, the ability to suppress the formant is strong, and the self-vibration energy caused by transient over-operation of the transient shock response cancels each other, making the device not Any shaking or vibration will occur.

 What are the characteristics of rubber shock absorbers?

1. The self-oscillation frequency is low;

2, long service life, can resist oil and water erosion, and will not be affected by temperature;

3. High stability and accurate test data;

4, easy to process production, small changes in characteristics; rubber shock absorbers in the low-frequency shock absorption effect is better than other vibration isolation devices, its existence and utilization value is higher than rubber isolators.

    In general, rubber vibration isolators and rubber shock absorbers are intercommunicating but different. They are made of rubber, but they are made of different structures to achieve the weakening of vibration. But they are all in the shock absorption industry.
