OPTIMAL DYNAMIC PARAMETER SELECTION FOR A STOCHASTIC WHEEL SUSPENSION MODEL UPON PASSANGER'S COMFORT

Abstract

The object of the paper is to provide a method which is able to design optimal dynamic parameters for car suspension systems. The mechanical model is a two-degree-of-freedom damped system which is excited by stochastic geometrical loading. The type of loading is a band limited (pink) noise generated by a realistic road surface. The model represents a wheel suspension system of a vehicle. The aim of the optimization is to define the road type-dependent damping and stiffness parameters of the suspension system which may provide the maximal passanger's comfort. The method is illustrated by a numerical example.
