A shock absorber is basically a hydraulic damping mechanism to control the vibrations of the spring. It controls spring movements in both directions: when the spring is compressed and when extended, the amount of resistance required in each direction is determined by the type of vehicle, the type of suspension, the location of the damper in the suspension system and the position in which it is mounted. Shock absorbers are a critical product that determines the character of a car, not only by improving the quality of driving but also by the operation to control the attitude and stability of the car body.
The damping mechanism of a damper is viscous damping. Viscosity is the property of a fluid by virtue of which it offers resistance to the movement of one layer over the adjacent one. The main components of a viscous damper are the cylinder, the piston and the viscous fluid. There is a play between the walls of the cylinder and the piston. The further the distance will be the velocity of the piston in the viscous fluid and will offer less value of coefficient of viscous damping. The basic system is shown below. The damping force is opposite to the speed direction.
