Rubber are used as vibration absorbers because, in their unstretched state, their molecules are coiled and can be stretched. … During vibration, it can store vibrational kinetic energy and releases slowly. Due to this, they possess elastic histerasis. So, rubbers are used as vibration absorbers.
In vibration analysis, a dynamic vibration absorber, or vibration neutralizer, is a tuned spring-mass system which reduces or eliminates the vibration of a harmonically excited system. Rotating machines such as engines, motors, and pumps often incite vibration due to rotational imbalances.
Because it’s a visco-elastic material, it absorbs, isolates, and reduces vibrations simultaneously. It is capable of absorbing nearly 95% of shock energy and reducing more than 50% of vibration energy. Sorbothane performs well in nearly every industrial application.
