Suspension Reasoning

For automotive applications, a vehicle suspension allows the controlled movement of the wheels relative to the vehicle body. In order to control it, passive, semi-active and/or active components are introduced. These enable the suspension system to adapt to various driving conditions. In most vehicles, this is achieved with a passive compliant structure (suspension). The vehicle suspension system consists of wishbones, springs, and shock absorbers to transmit and filter all forces between the body and road. If a vehicle has a passive suspension it will tend to oscillate under given inputs. To reduce the amount and duration of oscillation, some form of damping is required.
