摘要/Abstract

摘要： 轮对偏磨是铁道车辆常见的车轮磨耗形式。对国内某地铁线路的车轮磨耗进行测试分析，发现该线路车辆存在严重的车轮偏磨现象，左侧车轮以轮缘磨耗为主，右侧车轮以踏面磨耗为主。该地铁线路小半径曲线多，且左、右曲线分布严重不均，以及车辆不掉头运行是造成车轮偏磨的主要原因。基于UM动力学软件建立车轮磨耗预测模型，利用地铁车轮磨耗测试结果对磨耗预测模型进行验证，根据数值仿真结果提出轮对偏磨的解决措施。仿真结果表明，车辆掉头行驶能明显减缓车轮的偏磨现象，最佳掉头运行里程数为2×10⁴~4×10⁴ km。小半径曲线占比对车轮磨耗影响较大，左、右曲线百分比差值小于3%时可不采取掉头措施。

Abstract: The partial wear of wheelset is a common form of wheel wear for railway vehicles. Through a wheel wear investigation of a certain metro line in China, a significant partial wear phenomenon is observed. The left wheels are mainly worn on the flange, while the right wheels are mainly worn on the tread. The principle causes of the wheel partial wear are that the metro line possesses many small radius curves, the distribution of the left and right curves is severely uneven, and the vehicles don't reverse periodically. In order to mitigate the wheel partial wear, the wheel wear prediction model is established based on the UM dynamics software, which is verified by the metro wheel wear measurement results. According to the numerical simulation results, the solutions of the wheel partial wear are proposed. The vehicle periodical reversion can significantly mitigate the wheel partial wear, and the optimal reversion mileage is 2×10⁴-4×10⁴ km. The proportion of the small radius curve has a great influence on the wheel wear. It does not need to take the measure of periodical reversion when the percentage difference between the left and right curves is less than 3%.

Key words: metro vehicle, wheel wear, partial wear, numerical simulation, small radius curves
