摘要
本文论述了机车车辆通过道岔时轮对与辙叉相互作用的机理,建立了简化的计算模型.在此基础上,应用轮轨冲击力计算方法,分析了时速140km/h列车对道岔的冲击影响.根据计算,建议当列车速度提高至140km/h后,辙叉容许垂直磨耗应限制在4mm以内.
The interaction mechanism of the train with the railway switch on passing through the truck is studied and the simplified computational model is established in the paper. Based on the discussion, the impact effects of the train with speed of 140km/h on railway switch is analyzed by using calculational method for wheel/rail impact force. In light of the computation, the tolerated vertical wear and tear for railway switch is suggested to be 4mm in the case of the train speed increased to 140km/h.
