This Demonstration considers a quarter vehicle model comprising a tire, spring, damper and body mass. The plots represent the vertical displacements (m) of both the body mass and the unsprung mass (tire).

The system can be represented by two equations of motion:

and

.

As increases, the oscillating response increases in both magnitude and duration. Damping causes the system to eventually settle at 0. Specific parameters for a vehicle determine its response to various road conditions.
