摘　　要：以陕西韩城悬挂式单轨交通一号线车辆为研究对象,分析了悬挂式单轨车辆的结构特点及走行原理,并基于多体动力学理论,利用计算机仿真软件建立了具有66自由度的悬挂式单轨车辆动力学模型.为了体现橡胶走行轮的非线性特征,走行轮采用了Pacejka模型.结合悬挂式单轨车辆与传统铁道车辆的区别,通过仿真计算,对车辆的悬挂参数进行了优化,并提出了悬挂参数的取值建议,为国内悬挂式单轨交通的车辆选型及工程建设提供了重要的参考依据.The paper selects the suspended monorail in Hancheng as the research object, and then the structural features and running principle of the vehicle are analyzed. Based on multi-body dynamics theory, a 66-DOF dynamics model of suspended monorail is built by computer simulation software. In order to show the nonlinear characteristics of rubber traveling wheels, Pacejka wheel model is adopted. Considering the differences between suspended monorail and conventional railway vehicle, suspension parameters of the ve-hicle are optimized by simulation analysis. Meanwhile, the recommended values of suspension parameters are proposed. This paper provides important references for domestic suspended monorail vehicle type selec-tion and engineering construction.
