When a solid vibrates, the method of dissipating the vibration energy of the solid in the damping layer as much as possible is called damping shock absorption. Damping refers to the function of blocking the relative motion of objects and converting the motion energy into heat energy or other energy that can be dissipated.

The basic principle of damping shock absorption, the role of damping are:

(1) damping can reduce the vibration amplitude of mechanical structures, thus avoiding structural damage caused by dynamic stress reaching the limit.

(2) Damping is helpful for the mechanical system to quickly recover to a stable state after an instant impact.

(3) Damping can reduce the acoustic radiation caused by mechanical vibration and mechanical noise.

(4) It can improve the machining accuracy, measuring accuracy and working accuracy of various machine tools and instruments. All kinds of machines, especially precision machine tools, need high seismic resistance and dynamic stability when working in dynamic environment, and their dynamic performance can be greatly improved through various damping treatments.

(5) Damping helps to reduce the ability of the structure to transmit vibration.

The damping parts in the damping structure are basically in elastic state, which can mainly provide an excellent enough stiffness or damping for the main structure, so that the damping structure can effectively meet the normal use. ...

Under different vibrations, the components of the damping device can take the lead to enter the energy-consuming working state, effectively generating large damping, so that the energy input to the structure is largely dissipated, and the dynamic response of the structure ... When the solid vibrates, the energy generated during the solid vibration can be dissipated by the damping layer as much as possible. This method is called damping.
