Performance Evaluation of a Full Vehicle with Semi-Active MR Suspension at Different Tire Pressure

This paper presents the performance of a full vehicle MR suspension system at different tire pressure. The pressure of tire is related to tire stiffness, which is significantly affects the performance of suspension system. Therefore, in this research, the effectiveness of tire pressure on full vehicle MR suspension is evaluated. As a first step, the characteristic of tire with respect to pressure is experimentally tested and modeled. After that, the governing equation of MR damper and full vehicle MR suspension system are derived. The skyhook controller is implemented and the vibration control performance of full vehicle MR suspension is evaluated via simulation with respect to the tire pressure.
