摘要
介绍了运用货车120km/h动力学性能试验概况。试验对货车轮对、斜楔主摩擦板、承载鞍顶面磨耗和旁承间隙进行了不同水平设置,对各种货车进行了动力学性能测试。基于对试验数据的分析,研究货车各部件磨耗对运行安全性的影响。
This paper introduces the general situation of the dynamic performance test for 120km/h freight cars.Different settings are carried out for freight car wheel,oblique wedge main friction plate,carrying-saddles abrasions and side bearing gap.Dynamic performance tests are carried out on all kinds of freight cars.Based on the analysis of the test data,the wear influence of freight cars’ various parts on running safety is studied.
