%X 考虑走行轮胎的侧偏效应和滤波效应，使用线性轮胎模型建立了中央导向的单轴轮胎走行部自动导向捷运系统（APM）车辆的动力学方程和Simulink仿真模型，并仿真分析了导向轮与导向轨不同接触状态对APM车辆的曲线通过性能和运行平稳性的影响.仿真结果表明：导向轮设置初始预压力不会明显改善曲线通过性能，但会显著恶化APM车辆的横向平稳性；导向轮与导向轨的间隙增加了通过曲线时走行轮的侧偏力和导向轮的导向力.综合考虑曲线通过性能和横向平稳性，导向轮与导向轨之间应留间隙，但需要控制在0~5 mm.</br>The dynamical equations of an automatic passenger mover(APM) vehicle with middle guiding single axle tire running gears were derived by using linearized tire model, in which side force and rolling contact effect on running tire were taken into account. A simulation model of APM vehicle based on Simulink environment was built with object oriented programming technique, and the effects of contact statues between guiding tire and rail on curving performance and ride quality were studied. The simulation results show that the preload force on guiding tire do not improve curving performance but significantly worsen lateral ride quality, whereas the gap between guiding tires and rail will increase the running tire side force and guiding tire radial force on curve. The gap between guide tires and rail should be controlled in the range of 0~5 mm considering the curving performance and ride quality of APM vehicle
