从相对于圆弧、圆锥路面形状的输入能量和几何蛇行运动波长两个方面，对于车轮路面形状对高速动车运动特性的影响进行了评价。通过动车的运动模拟得知，对于已实现无摇枕化且车体变为柔性支承的新型高速新干线动车来说，有时采用圆弧踏面要比采用圆锥踏面在抑制蛇行运动、提高稳定性方面更为有利。并对其原因进行了探讨。在影响圆弧踏面车轮运动的主要因素方面与圆锥路面进行了对比研究。在求取车体振动衰减比的同时，还求了从钢轨输入到动车的能量。并从几何蛇行运动波长和车体固有频率的关系方面进行了考察。通过分析表明，采用圆弧路面车轮在高速（270km／h）运行时与采用圆锥踏面车轮相比，其转向架蛇行运动波长短，频率高，且远离了较低的车体固有频率。另外，由模拟计算了从钢轨到动车的输入能量，验证了车体固有频率与蛇行运动特性之间关系的正确性。由轮对横向位移的变化表明，圆弧踏面从钢轨得到的能量要小于圆锥踏面从钢轨得到的能量。
The influence of wheel shape on the movement characteristics of high-speed motor car was evaluated from two aspects: input energy of circular arc and conic shape and wavelength of geometric meandering motion. According to the motion simulation of the motor car, it is known that for the new high-speed Shinkansen motor car that has no bolstering and the car body becomes a flexible support, the use of the circular arc tread is sometimes more effective than the use of the conical tread in suppressing the meandering motion and improving the stability More favorable. And the reason is discussed. In the impact of the arc tread wheel movement of the main factors with the cone road were compared. In seeking the body vibration attenuation ratio at the same time, also obtained from rail input to the motor car energy. The relationship between the geometric meandering wavelength and the natural frequency of the car body was also investigated. The analysis shows that, compared with the conical tread wheel, the bogie has shorter wave speed, higher frequency and far away from the lower natural frequency of the vehicle when using the circular road wheel running at high speed (270km / h). In addition, the input energy from the rail to the motor car is calculated by simulation, which verifies the correctness of the relation between the car body natural frequency and the meandering motion. The change of the lateral displacement of the wheelset shows that the energy of the arc tread obtained from the rail is less than the energy of the cone tread obtained from the rail.
