摘要

高寒动车组运行环境恶劣，给动车组轮轨间的粘着利用控制带来了很大的挑战。提出了一种针对高寒动车组粘着力矩快速平稳恢复的方法，既保障了动车组在恶劣冰冻天气下的平稳运行以及乘坐舒适度，又能最大可能利用轮轨之间的粘着，保障了动车组的准点率。通过高寒动车组线路试验以及实际运行数据表明，在发挥动车组轮轨最大可用粘着的条件下，该恢复策略能很好地减少动车组发生二次空转滑行的概率。

Abstract

The bad operation environment of the high-speed EMUs is a big challenge to adhesion control of the rail between the wheel and rail. A method of rapid and stable recovery method in re-adhesion for high-cold EMUs was proposed, which could ensure the smooth operation of the EMUs in the severe freezing weather, the comfort level, and the maximum utility of the adhesion between the wheel and rail to ensure the punctuality of the EMUs. Through the experimental in the high-cold EMUs line, the actual running data showed that the method could reduce the chance of second slip/slide of EMUs in the case of the maximum available adhesion of the wheel and rail.
