Abstract: This paper proposes a semiactive controllable magnetorheological (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 equations of the model are derived by considering engine excitation force, and a semi-active skyhook controller is designed to attenuate unwanted vibrations. The controller is then 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.
Keywords: magnetorheological fluid; engine mount; skyhook control; vibration control; hardware-in-the-loop simulation.
