Dynamics of Automobile Suspension Systems
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).[more]
The system can be represented by two equations of motion:
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.[less]
Snapshot 1: hard damping
Snapshot 2: weak dampening
Snapshot 3: long time behavior
