Quarter-car suspension models are used to study the dynamics of a vehicle’s suspension. The model consists of: the wheel, the suspension system (damper and coil) and a quarter of the vehicle’s body mass. The quarter car has been for a long time the par excellence model used in suspension design. It is a very simple model as it can only represent the bounce motion without taking into account pitch or roll vibration modes. However it is very useful for a preliminary design.[1] This paper discusses the suspension dynamics evaluated using a quarter-car simulation of an in-wheel SRM EV and compares it to the internal combustion engine (ICE) vehicle.
