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。介绍了劳尔有轨电车动力走行部和拖动走行部的结构,分析了其导向机理:设置于走行轮前方的导向轮和导向杆迫使走行轮胎产生了偏转角,由此产生的侧偏力迫使车辆沿着轨道运行。使用线性化的轮胎模型建立了动力走行部和拖动走行轮的动力学方程,发现劳尔有轨电车的导向运动类似一个有阻尼的单摆运动。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,对导向的稳定性有着重要的影响。Translohr tram uses tyres as the running wheels, steel rollers and arms as the guiding mechanics. The steer- ing mechanism is analyzed according to the structure of the running gear of Translohr tram： the running wheels are ro- tated around vertical axis by the guiding rollers and arms on forward direction, and the vehicles are steered to guiding rail by the side leaning forces of running wheels. The dynamical equations of power and trail running gear of Translohr tram are established based on the linearized tire model. It is found that the guidance motions of both power and trail running gear are similar to that of a pendulum. The natural frequency of guidance motion is related with the side leaning stiffness of tire and the length of guiding arm, the damping ratio of guidance motion is relied on the side leaning stiffness of tire, the length of guiding arm and the forward velocity. Among them, the length of guiding arm is the key parameter for stable guidance.
