What role do shock absorbers play on cars?

Dampers are primarily used to suppress the vibrations and impacts from the rebound of the spring after absorption and the shocks from the road surface. While shock-absorbing springs can filter out the vibrations from the road, the springs themselves still undergo reciprocating motion, and the dampers are designed to suppress this spring bounce. Dampers are not used to support the vehicle's weight; instead, they inhibit the vibrations after spring absorption and absorb the energy of road impacts. Springs serve to mitigate impacts, transforming a "large energy single冲击" into "small energy multiple impacts," and the dampers gradually reduce these "small energy multiple impacts." If you've driven a vehicle with faulty dampers, you can experience the car's bouncing after each pothole or bump, and it is the dampers that are designed to suppress this bouncing. Without dampers, the rebound of the spring cannot be controlled, causing severe bouncing on uneven roads and a loss of tire grip and stability during turns.
