摘　　要：文章介绍了各种回转方式的APM车辆走行部结构,并使用Simpack软件建立了簧上回转和簧下回转APM车辆的动力学模型,其中走行轮轮胎采用Pacejka模型,导向轮轮胎采用单边间隙力元模拟。仿真分析了簧上回转和簧下回转的APM车辆的曲线通过性能。仿真结果表明:在圆曲线上,簧上回转方式的APM车辆的走行轮处于径向位置,在圆曲线上走行轮的侧偏力基本为零;簧下回转方式的APM车辆的走行轮不能达到径向位置,一直存在着侧偏力,并随着曲线半径的增大而减小。The typical running gears with different rotating arrangement are presented in paper, and the dynamics models are established based on Simpack software in which the Pacejka model and unilateral clearance force clement were utilized to imitate the running tire and guide tire respectively. The curving performance of the APM vehicle with different rotating arrangement are analyzed. The running wheels of the APM vehicle with up- spring rotating mode can stay at radial position on circular curve, and the cornering forces of the running tires are nearly zero. The running wheels of the APM vehicle with under-spring rotating mode can not reach at radial position on circular curve, and the cornering forces of the the increase of the curve radius. running tires still keep a certain value and decrease with
