Elastic damping is a nonlinear viscous damping, commonly used in vibration damping, which can explain the physical concept of elastic damping. It is the combination of linear damping and nonlinear damping. In comparison to the continuous damping, elastic damping usually offers larger damping at larger deflection, and smaller damping at smaller deflection.

Elastic damping is widely used in suspension system and vibration control system due to its reliable performance, relatively simple structure and good damping effect. It works by using an elastomer, such as rubber, to absorb and dissipate the vibration energy. When the elastomer is subjected to flexure and shear, it will produce viscous and hysteresis damping. With the introduction of nonlinear elastic damping, the vibration of the system will be effectively and quickly damped out.

In electromagnetic suspension systems, the elastic damping is often used to reduce the voltage amplitude of the instability which is caused by the motion of the magnet core. Besides, elastic damping can also be used in automatic control systems, such as vibration isolation, shock absorption, and dynamic balancing. It is also used in other areas, such as aerospace and motor vehicles.

In short, elastic damping is capable of compensating for the effect of different elasticity, and providing damping reaction to keep the system controlled. It is a very important part of vibration damping and control system.
