What is the difference between a buffer and a damper

A shock absorber and a damper are both devices used to reduce the impact and vibration generated during the operation of machinery and equipment, but their working principles and application scenarios are slightly different.
The main function of a shock absorber is to slow down the impact force and vibration amplitude by absorbing and dispersing energy when machinery and equipment are subjected to impact or vibration, thereby protecting machinery and equipment and reducing the noise level. Shock absorbers are usually made of materials such as springs, hydraulics, and air pressure, and have a large buffering force, making them suitable for larger impacts and vibrations.
The main function of a damper is to reduce the vibration amplitude and vibration time by consuming the vibration energy of machinery and equipment, thereby achieving the purpose of shock absorption. Dampers are usually made of friction materials, liquids, or gases, and have a small damping force, making them suitable for small amplitude vibrations.
Therefore, the selection of shock absorbers and dampers should be based on actual conditions, and suitable devices should be selected according to the working conditions and vibration characteristics of the equipment to achieve the effect of reducing impact and vibration.
