Abstract
The article describes the development process and the overall performance of a semi-active suspension, using a rotary MR damper controlled by on-off strategy in suppressing acceleration transmitted to a vehicle. To determine the off-state damping coefficient and the MR force activated, an off-road vehicle single wheel suspension system dynamics model was developed and tuned within a Matlab/Simulink environment. After a preliminary virtual analysis, a set of semi-active suspension test system comprised of one MR damper, associated sensors and controller, was characterized in time and frequency domain. The experimental results demonstrate that the semiactive suspension is effective for suppressing vehicle vibration and that is simple and offers robust suspension performance. The theoretical and experimental results are demonstrated to be in good agreements.
