The role of damping is mainly in the following five aspects:
1. Damping reduces the resonance amplitude of the mechanical structure, so as to avoid structural damage caused by the dynamic stress of the structure;
2. Damping helps the mechanical system to quickly return to a stable state after being subjected to instantaneous impact;
3. Damping can reduce the 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. All kinds of machines, especially precision machine tools, need to have high seismic resistance and dynamic stability when working in a 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.
1. When the solid vibrates, the method of dissipating as much of the energy of the solid vibration as possible in the damping layer is called damping and shock absorption;
2. Damping refers to the effect of hindering the relative motion of objects and converting the motion energy into heat energy or other energy that can be dissipated;
3. The "special" components placed on the structural system can provide the resistance of movement and dissipate the movement energy, which we call the damper.
The damping sheet is a viscoelastic material attached to the inner surface of the body, which is close to the steel wall of the body, mainly to reduce noise and vibration, that is, to play a damping role. All cars are equipped with damping plates, such as Mercedes-Benz, BMW and other brand cars. In addition, damping sheets are also used in aerospace vehicles, airplanes, and other machinery that requires shock and noise reduction.
