摘要：
A height adjustable hydraulically interconnected suspension was proposed for actively adapting road condition changes. Parameters of the hydraulically interconnected suspension were optimized to make the vertical stiffness of a vehicle with this suspension keep the same as that of the original vehicle. Based on the hierarchical control theory, a switching control strategy for the height adjusting of vehicle body was adopted. Based on CarSim, AMESim and Matlab/Simulink simulation platforms,a joint simulation system including a vehicle multi-body dynamic model and a control model was established. The simulation analyses for switching processes, ride comfort and handling stability were performed. The results indicated that this system is able to adjust adaptively the height of vehicle body, and improve the handling stability of vehicle, in the premise of simultaneously keeping vehicle's ride comfort. © 2018, Editorial Office of Journal of Vibration and Shock.
