【Abstract】 Magnetorheological (MR) damper, which can provide controllable damping forces with very little energy consumption, is proposed to be used in semiactive control vehicle suspension system. Three different strategies are used to compare and verify the validness of semiactive control suspension system, and a strategy based on optimal control theory is proposed and recommended. Road excitation of B level is utilized in numerical simulation. Numerical results presented here demonstrate that the strategy based on optimal control theory is very effective. Furthermore, MR damper is a ideal semiactive control device with great potential.更多还原
