Active systems in the vibration control of vehicles

The optimization procedure for the vibrocontrol system of a vehicle is presented. The vehicle is represented by a two degrees of freedom model with discrete parameters. Input random kinematic excitation is assumed to be stationary and ergodic. The elektrohydraulic compensator is working parallely with the conventional suspension system. The structure and parameters of the active part, respectively, were obtained for the optimum criterion taken as a quadratic form. The relationships between values of the system parameters and the coefficients that describe fahr comfort and fahr safety are discussed.
