To accelerate the attenuation of vibrations between the chassis and body, thereby improving ride smoothness (comfort), shock absorbers are installed within the suspension system of most automobiles.
A car's shock absorption system consists of springs and shock absorbers. Shock absorbers are not used to support the weight of the vehicle body, but rather to suppress the oscillations caused by the springs absorbing shocks and to absorb the energy of road impacts. Springs mitigate impacts, transforming a "large-energy single impact" into "small-energy multiple impacts," while shock absorbers gradually reduce these "small-energy multiple impacts." If you've ever driven a car with damaged shock absorbers, you can feel the lingering bounce after each pothole or undulation; shock absorbers are precisely used to suppress this bouncing. Without shock absorbers, the spring's rebound cannot be controlled, resulting in severe bouncing when encountering rough roads, and loss of tire grip and traction during cornering due to the spring's up-and-down oscillations.
