| 摘 要： | 采用车辆－轨道耦合动力学理论及其相应的动力学仿真软件TTISIM，分别对锥形（TB型）和磨耗形（LM型）踏面车辆与轨道的动力学性能进行理论仿真计算，并对计算结果进行了详细的比较。结果表明：LM型跳面有利于车辆动态曲线通过；TB型踏面对提高车辆蛇行失稳临界速度有利；两种类型踏面车轮对车辆在直线轨道上的平稳性差别甚小。

| Abstract: | With the theory of vehicle track coupling dynamics and the simulation software TTISIM, dynamic performances of vehicles with the cone and the worn profiles, respectively, are calculated and compared in detail. The results show that the worn profile wheels perform better on curve tracks, while the cone profile wheels have higher critical speed of hunting stability. There is not obvious difference in carbody vibration of vehicles with the two type profiles running on tangent tracks. |
