| 摘 要： | 通过对装配锥型踏面和LM磨耗型踏面轮对的捣固车分别进行正线动力学性能对比试验数据分析表明,锥型踏面轮对的捣固车直线动力学运行平稳性优于LM磨耗型踏面轮对的捣固车,但LM磨耗型踏面轮对的捣固车通过侧线、曲线的脱轨系数和轮轴横向力等稳定性能优于锥型踏面轮对的捣固车。

| Abstract: | The dynamics performances of tamping machine which was equipped with cone-type tread and LM worn tread respectively were test on the railway line.It was indicated from the contrast test results that the running stability of tamping machine with cone-type tread is better than that of vehicle with LM worm tread.However,the derailment coefficient and wheel-axle lateral force of tamping machine with LM worn tread is better than that of vehicle with cone-type tread when the vehicle is running through the lateral... |
