The shock absorber is mainly composed of a spring and a damper. The function of the spring is mainly to support the weight of the car body, and the damper is to reduce the vibration. The damper is a man-made object motion attenuation tool. In order to prevent objects from being suddenly shocked, damping has a wide range of applications in our real life, such as automobile shock absorption systems. When the swing door is opened, it can be slowly closed and so on.
Under normal circumstances, when the spring is squeezed by an external force, it will strike back in the direction of the force. When the external force disappears, the spring will immediately return to its original shape. At this time, the body will shake to a certain extent due to the influence of inertia. If there is no damping to play a role in it, every time the car crushes a stone, there will be greater fluctuations, which will cause greater discomfort to the driver and passengers. The function of damping is to slow down the compression and recovery rate of the spring, and slowly reduce the rapid recovery effect, so that the spring does not produce a large impact when returning, and it is gradually weakened by the method of layer by layer. adapt.
Hydraulic shock absorbers are relatively demanding in terms of work, especially for the sealing problems of the component system, otherwise there may be oil leakage. In addition, hydraulic shock absorbers use the compressibility of liquids and the characteristics of liquids to absorb energy when compressed and dissipate energy when flowing to realize shock absorbers for the purpose of reducing or eliminating vibration.
