Abstract
In order to ensure the driving safety (the anti-roll performance) of vehicles when steering and the ride comfort when passing through uneven roads, this chapter proposes the principle and configuration of a novel reciprocating rotary damper based on a smart material-magnetorheological (MR) fluid with a large controllable torque range and a semi-active stabilizer bar system based on the MR damper. The dynamic model of the MR semi-active stabilizer bar system is established. The mathematical model of the proposed MR damper is derived, and the corresponding controllable torque characteristics are obtained and evaluated using the finite element analysis results via software ANSYS. A piecewise control strategy with respect to vehicle body roll angular velocity is proposed, and a preliminary control of MR stabilizer bar is conducted and compared with the passive-on stabilizer bars on the vehicle anti-roll performance.
