The primary function of the damper on the vehicle is to damp the sprung and unsprung masses at their resonant frequencies. For the sprung mass, this includes the pitch, heave and roll resonant frequencies.
In view of the tremendous worldwide production of automotive dampers (shock absorbers), the former absence of a book devoted to this topic is surprising. During some years of damper design, research and commercial testing, the author has become aware of a need for a suitable book to present the

The main function of the dampers is to control the transient behavior of the sprung and unsprung masses of the vehicle. This is accomplished by damping the energy stored in the springs from suspension movement. The damper generates a force defined by the characteristic curve and the velocity of the damper.
There are three basic types of suspension components: linkages, springs, and shock absorbers. The linkages are the bars and brackets that support the wheels, springs and shock absorbers. Springs cushion the vehicle by dampening shock loads from bumps and holes in the road.
