Abstract
A Simplified 4 DOF rolling vibration model and Simulink model for front suspension of E-bus are built. The dynamic response characteristics of body rolling, in the case of a lateral acceleration step-input and a single sine-input, are simulated respectively. The influences of some suspension parameters on the dynamic response characteristics of body rolling are analyzed. The analysis results showed that the increase of the stiffness of suspension or the stiffness of anti-roll bar can evidently reduce the average of body rolling angle. The increase of the damping of suspension can evidently reduce the overshoot of body rolling angle. For a normal turning condition of E-bus, the methods to reduce body rolling by increasing stiffness of air suspension system and controllable stiffness of anti-roll bar are feasible.
