摘要/Abstract

摘要： 为研究使用弹性车轮的车辆踏面以及运行弹性车轮的钢轨磨耗情况，基于Archard磨耗模型建立了轮轨磨耗预测模型，对不同轨道不平顺条件、不同曲线半径条件下的车轮踏面以及钢轨磨耗情况进行了分析。对比分析弹性车轮和刚性车轮，结果表明：在线路较差的情况下，弹性车轮具有更好的降磨效果；弹性车轮在曲线半径较小的线路上对磨耗的降低效果较小，随着曲线半径的增大，弹性车轮的降磨效果明显；运行弹性车轮时比运行刚性车轮时钢轨的最大累积磨耗量减小了33%；弹性车轮对曲线钢轨磨耗有一定的降低作用。

Abstract: In order to study the wear of vehicle treads with resilient wheels and rails of running resilient wheels, a prediction model of wheel and rail wear was established based on Archard wear model. The wear situations of wheel treads and rails were analyzed under different track irregularity conditions and curve radius conditions. Comparing and analyzing the resilient wheels and rigid wheels the results show that, the resilient wheels have better wear reduction effectiveness when the track is poor. The wear reduction effectiveness of resilient wheels on the track with smaller curve radius is smaller. With the increasing of curve radius, the wear reduction effectiveness of resilient wheels is obvious. Compared with running rigid wheels, the maximum cumulative wear of rails is reduced by 33% when running resilient wheels. The resilient wheels may reduce the wear of curved rails to some extents.

Key words: resilient wheel, low floor tram, wheel and rail wear, track irregularity
