Aim at simultaneously improving the safety (anti-roll performance) and ride comfort of vehicles during fast cornering or over road irregularities, the principle and configuration of magnetorheological (MR) semi-active stabilizer bar is proposed in this paper. The MR stabilizer bar featuring a rotary MR damper is used to provide small torsional torque at low speed to improve ride comfort, while large torsional torque to enhance the safety at high speed cornering. To verify the feasibility and effectiveness of the proposed MR stabilizer bar, the mathematical model of the dynamic system is established, and the passive-on control performance of a specific full vehicle is studied via a dynamics simulation software ADAMS, and the performance is compared with the conventional passive stabilizer bar for ground vehicle dynamic system.
