广州地铁LM型车轮踏面奇数轮缘厚度等级镟修研究

Study on Grade Lathing of LM-type Wheel Tread with Odd Rim on Guangzhou Metro

在地铁车辆现有偶数轮缘厚度等级基础上,通过安全性仿真计算、镟修试验和跟踪、平稳性测试等方法,研究增设奇数轮缘厚度等级的可行性,以减少在恢复轮缘厚度情况下所造成的车轮直径浪费,延长车轮使用寿命,降低车轮维修成本,提高车轮镟修经济性。研究成果可为地铁车辆推广奇数轮缘等级镟修提供参考。

Based on the existing even rim thickness grades of subway vehicles, through safety simulation calculation,lathing test and tracking, stability test, the feasibility of setting odd rim thickness grades is researched,to reduce the wheel diameter wastage in the rim thickness recovering,extend wheel life,cut wheel maintenance cost,and improve wheel repair economics. The research results can provide a reference for the promotion of the odd rim repair in the whole subway industry.
