摘　　要：汽车的操纵稳定性决定了汽车的操控性、行驶安全性和抗外界干扰能力,而转向系统与汽车操纵稳定性关系最为密切。为研究液压动力转向车辆的操纵稳定性,利用Matlab/Simulink建立了液压动力转向系统以及整车三自由度状态方程的仿真模型,在使用试验数据验证仿真模型正确性的基础上,对模型进行了蛇行试验的操纵稳定性仿真,分析了液压动力转向系统的系统结构参数对蛇行试验的影响,仿真结果的分析为动力转向系统的设计和提高车辆操纵稳定性提供了依据。Handling and stability signifies vehicle＇s controllability,safety and resistivity to the exter-nal interfere.The steering systems have close relationship with vehicle＇s handling and stability.In order to research the handling and stability of the HPS vehicle,Matlab/Simulink is applied to build the HPS model and the three degree-of-freedom vehicle model.From the test,the simulation model is testified correct.Then analyze the influence of some structural parameters on vehicle＇s handling and stability through the handling and stability simulation.The study of the solution provide basis for the steering system＇s design and the im-provement of vehicle＇s handling and stability.
