The objective of this study is optimizing the components design of a vehicle suspension system under excitation due to road roughness. The vehicle is modelled as a dynamic system made of masses interconnected by linear springs and dampers. The optimizing code provides values corresponding to the characteristics of masses, dampers and springs which, within a range, minimize the objective function for a defined excitation. This objective function quantifies the vehicle comfort level. The optimization method used is the sequential linear programming by iteratively applying the Simplex algorithm. The model response is obtained in frequency domain and the vehicle excitation can be either random or deterministic. The exact nature of the optimization problem, objective function and restrictions, depend on the type of excitation considered. In this paper the problem formulation, together with a comparison with other authors, are presented. (TRRL)
