Vibration studies of a vehicle with controlled piezoelectric dampers

This paper is devoted to the study of the influence of piezoelectric damper control on vehicle vibrations. Reducing vertical vehicle vibrations improves ride comfort, while decreasing fluctuations in wheel pressure on the road increases vehicle traffic safety. Damping force control is performed using shock absorbers controlled by piezoelectric valves. The piezoelectric valve allows for the control of the damper’s characteristics by changing the flow resistance between the chambers of the hydraulic damper.VIBRATION INVESTIGATION OF A VEHICLE EQUIPED WITH CONTROLL PIEZOELECTRIC DAMPERS
In this paper an effect of damping force controlling in a vehicle suspension system is discussed. A vehicle suspension system is equipped with controlled piezoelectric dampers which allow controlling vehicle body vibration. Vertical vibration limitation of vehicle body has an influence on comfort and safety by decreasing a value changes in wheel contact forces. Control of friction in dampers is realized by controlling piezoelectric valve and flows between chambers of damper. (…)
