| 摘 要： | 列车蛇行运动是造成列车悬浮脱轨事故的主要原因,随着列车速度的不断提高,悬浮脱轨事故频有发生。通过对车辆车轮与轨面间的动力学原理分析,结合科研部门的大量试验数据,提出减小直线段轮轨间隙(名义公差)是防止空车悬浮脱轨的有效方法。

| Abstract: | Train snake movement is the major reason for suspension derailment.Through the dynamics analysis on the relationship between wheel and rail surface,based on the experimental data from scientific research institutes,we find the effective measure to avoid suspension derailment of empty trains that is to reduce the gap between rail and wheel in straight section(nominal common difference). |
