摘　　要：劳尔有轨电车是一种依靠轮胎走行、钢轮导向的新型有轨电车。劳尔有轨电车的动力走行部位于车体端部,拖动走行部位于连接模块,车体之间铰接在连接模块。文章建立了劳尔有轨电车的简化动力学模型:每个车体包括横移和摇头两个自由度,走行部简化为单个轮胎和一个无质量的导杆。建立了劳尔有轨电车的单车动力学方程和稳态曲线通过方程。研究发现劳尔有轨电车导向运动的频率取决于走行轮胎的侧偏刚度和导向杆长度,运动的阻尼比取决于走行轮胎的侧偏刚度、导向杆长度和前进速度。导向杆长度是影响导向性能的关键参数,文章讨论了导向杆长度的合理取值方法和范围。Translohr tram is a new urban rail transit vehicle with tyre running gears using a middle single rail guiding system. The power running gears locate under end module,the trailer running gears locate under connecting module,and the car body modules are articulated through connecting module. This paper presents a concise dynamic model of Translohr tram. Each car body includes lateral and yaw motion degrees,and the running gear is simplified as a single tyre and an massless guiding rod. The dynamic equation of single car body and the equation for steady state curve are derived. It is found that the frequency of guidance motion is related with the cornering stiffness of tyre and length of guiding rod,and the damping ratio is relied on the cornering stiffness of tyre,length of guiding rod and forward velocity. The length of guiding rod is a key parameter for stable guidance and the reasonable length of guiding rod is discussed in this paper.
