- In this paper an effect of controlling damping force in a vehicle suspension system is discussed. A vehicle suspension system is equipped with controlled piezoelectric dampers (PZD) which allow controlling vehicle body vibration. The main goal of performed and presented in the paper studies was to determine the properties of piezoelectric damper and propose control strategy. As piezoelectric damper was used hydraulic cylinder with piezoelectric valve controlling flows between chambers of the damper. Some results of experimental studies of the damper dissipation characteristics were obtained and are presented. Vertical vibration reduction of vehicle body has an influence on comfort and safety by decreasing a value in wheel contact forces variation. Control of friction in a vehicle suspension system can be realized by controlling piezoelectric valves and flows between chambers of the PZD dampers. In this paper also some algorithms of vibration control are proposed and discussed. The main goal of this paper is to investigate issues associated with control algorithms for an adaptive (semi-active) suspension system of a vehicle equipped with new type of semi-active dampers. The paper presents results of numerical simulations of a vehicle suspension system equipped with a piezoelectric damper.
