非独立悬架轻型客车操纵稳定性仿真分析(一)

Simulation and Analysis on Handling Stability of Dependent Suspension Light Duty Bus(Ⅰ)

以前后悬架均为钢板弹簧非独立悬架的某轻型客车为研究对象,利用ADAMS/Car模块,建立起整车动力学仿真模型,并对该车进行了方向盘转角阶跃输入仿真试验,同时分析了前后悬架钢板弹簧刚度对汽车转向特性的影响,提示了钢板弹簧刚度和操纵稳定性的内在联系。

This paper aims at a light bus both front and rear suspension with leaf spring structure. Using ADAMS/Car module,a full vehicle dynamic model is built. By means of the step angle input of steering wheel,this paper analyzed the impact of front and rear suspension leaf spring stiffness on steering characteristics. It presents the relationship between leaf spring stiffness and handling stability performance.
