| 摘 要： | 随着速度的不断提高,轮轨接触关系对列车运行安全性的影响越来越大。当轮轨型面发生损伤后,轮轨非对称接触现象就会产生。轮轨非对称接触现象不仅影响车辆运行的安全性,同时与车轮型面损伤问题也有着密不可分的关系。文章以SS3B型机车为例,建立了由轮轨型面磨耗和轮径差导致的轮轨非对称接触的模型。仿真结果表明当轮轨非对称现象发生后,机车的抗蛇行运动临界速度就会降低,同时,曲线通过的脱轨风险性也会显著增大。 |

| Abstract: | The influence of the wheel/rail contact relation to the running safety of the train has turn more and more big with the increase of the train running speed.When the wheel/rail surface damage occurred,the wheel/rail unsymmetrical contact was formed.The unsymmetrical wheel/rail contact was not only influence the running safety of the train,but also has a big relation with the wheel surface damage problem.Take type SS3B locomotive for example,the unsymmetrical wheel/rail contact model which caused by the wheel... |
