摘　　要：考虑到跨座式单轨车辆通过曲线时主要靠导向轮来导向,导向轮径向力大小是评价单轨车辆曲线通过性能的一个重要指标。运用多体动力学仿真分析软件ADAMS建立单轨车辆仿真模型。在轨道半径和超高都不变的情况下,车辆以恒定的速度运行,通过改变走行轮垂向刚度的大小来分析导向轮所受径向力情况以及对车辆曲线通过性能的影响。单轨车辆仿真分析研究表明,走行轮垂向刚度的大小对车辆的曲线通过性能有很大影响。The straddle-type monorail vehicle was mainly guiding by the steering wheel when it throughing the curve.Therefore,the size of steering wheel's radial force was an important index to evaluate the curve negotiation performance of monorail vehicle.Simulation model of monorail vehicle based on the multi-body dynamics simulation analysis software-ADAMS was established.Under the condition of orbit radius and super-high no changing and vehicle running with constant speed,radial force characters of steering wheel and its impact on curve negotiation performance of vehicle were analyzed by changing the size of the running wheel's vertical stiffness.The simulation and analysis showed that running wheel's vertical stiffness had great influence to vehicle curve negotiation performance.
