Abstract This paper studies the responses of the quarter car and a half car model as the vehicle ride performance is generally assessed at the design stage by simulating the vehicle response to road excitation. This requires the development of a vehicle model to analysis its responses. The disturbances from the road are assumed to be constant or step function and the time responses and frequency responses of the sprung and unsprung masses have been studied. Simple yet, in practice, meaningful state-space formulations of the optimal suspension control problem for a half-car 2-D and 4-D vehicle model are given. Using an efficient equivalent representation, a complete analytical solution of the system was obtained. The optimal solution here is the damping, which has been optimised with the given set of fixed parameters. This paper provides an insight on the suspension dynamics of the two most extensively used models in vehicle dynamics with their complete state space realization, simulated using the MATLAB platform.
