Abstract

Abstract

In order to decrease the wastage of external energy for active suspension, a self-powered active suspension(SPAS) was designed, a reduced half carbody lateral suspension dynamics model of railway vehicle was established, the LQG controller was designed, the conditions insuring the energy balance of the suspension system were analyzed by using stochastic vibration principle, and its operating performances were simulated by Matlab/Simulink. The result indicates that self-powered active suspension has better isolated performance than semi-active and passive suspensions, and it realizes active vibration control and energy regeneration synchronously when the equivalent damping coefficient of DC motor actuator is greater than its critical value.
