Abstract

This paper proposes a semiactive controllable magneto-rheological(MR) engine mount for vibration control of a passenger vehicle. A mixed-mode type MR engine mount is devised and incorporated with a full-vehicle model. The governing equation of the model is derived by considering engine excitation force and a semiactive skyhook controller is designed to attenuate unwanted vibrations. The controller is implemented through a hardware-in-the-loop simulation(HILS) and control responses such as acceleration at the driver's position are evaluated in time and frequency domains.
