摘　　要：独立旋转车轮的结构型式与传统轮对相比具有很大的差别,在直线和曲线上的轮轨接触动力学性能也有明显差异。独立旋转车轮理论上不存在纵向蠕滑,具有较高的临界速度和较低的轮轨磨耗,其直线对中性能和曲线导向性能较差。利用计算机仿真,对独立旋转车轮和传统轮对的动力学性能进行了比较分析。As the difference in structure between Independently Rotating Wheels and traditional wheelset, the contact performance between wheels and track and dynamic characteristics is different. There is no logntitudinal creepage on Independently Rotating Wheels theoretically, so it has high critical Speed and low abrasion, but the performance of running back to center in the straight track and guiding in the curve is bad. In the dissertation compared the dynamic characteristics between Independently Rotating Wheels and traditional wheelset by computer simulation.
