Definition and function of shock absorbers
Shock absorbers, as the name suggests, have the function of reducing vibration. Academically speaking, when a vehicle passes over uneven road surfaces, the shock absorber spring can filter out the vibration of the road surface, but the spring itself will also have reciprocating motion. The function of the shock absorber is to suppress the vibration caused by the rebound of the spring after absorption and the impact from the road surface, in order to improve the smoothness of the car's driving.
