This paper describes the development of a continuously variable semi-active damper for heavy commercial vehicles. A high speed proportional valve allows the damping coefficient to be varied continuously. The influence of oil flow forces on the valve spool position control are investigated. A mathematical model of the damper is described and simulated results are compared with measured responses. The stop response of the damper is measured and the factors affecting speed of response determined. The force tracking performance of the semi-active damper is examined under realistic operating conditions using a Hardware-in-the-Loop testing method.
