Abstract:

In view of the difficulty in keeping balance between the handling stability and ride comfort of bus characterized by high mass center and heavy load, a novel suspension configuration is proposed, combining roll-resistant hydraulically interconnected suspension (RHIS) and electronically controlled air spring (ECAS). Firstly, a nonlinear model for ECAS is developed based on thermodynamic theory and verified by test. Then, 9-DoF vehicle dynamic model is derived based on centroid theorem and momentum moment theorem, and into which the model for RHIS is coupled. Next, a fuzzy controller for air spring is designed for body height adjustment. Finally, simulations on the test conditions of handling stability and ride comfort are conducted to compare the performances of novel suspension and traditional one. The results show that the novel suspension system proposed can achieve the three-levels of body height adjustment and apparently improve the handling stability of vehicle while maintaining the original level of ride comfort.
