When a railway vehicle is running on a steep curve section, the wheel flanges of the outside wheel are prone to ride on the rail top surface. In this study, a simulation method for numerical analysis of a railway vehicle running on a curved track with short radius at a relatively low speed is developed and some numerical examples are shown. It is concluded that the small difference between the relative longitudinal velocity of the right rail and that of the left rail generated by the turning motion of the vehicle plays an important role in the numerical analysis, and that the dropping of the wheel from the rail top may occur, in the case that the static wheel load of vehicle holds a large unbalance number and the friction at the contact surface between the wheel and the rail reaches to a certain high value.

铁路车辆在急弯路段行驶时，外侧车轮的轮缘容易骑在钢轨顶面上。在这项研究中，一个模拟方法的数值分析的轨道车辆运行在一个较短的半径在相对较低的速度曲线轨道上，并显示了一些数值例子。得出了车辆转弯运动产生的左右轨纵向相对速度之差在数值分析中起着重要作用的结论，并得出了车轮可能从轨顶脱落的结论，当车辆静轮重具有较大的不平衡数，轮轨接触面摩擦力达到达到一定的高价值。
