Damping has the following five main functions: 1. Damping can reduce the resonance amplitude of mechanical structure, so as to avoid structural damage caused by dynamic stress
2. Damping helps the mechanical system recover to a stable state soon after being subjected to a transient impact
3. Damping can reduce sound radiation caused by mechanical vibration and reduce mechanical noise
4. It can improve the processing accuracy, measurement accuracy and working accuracy of various machine tools and instruments
