本文以1:1列车制动综合试验台为研究对象,详细分析了制动工况下黏着特性相关的特征参数的测试方法,主要包括滑移率、黏着力以及正压力。最后利用试验台进行同一工况下的重复试验,通过数据整理及分析得出黏着滑移率关系曲线,证实了该1:1列车制动系统综合试验台能满足对制动过程中轮轨间黏着系数的测试。
In this paper, the 1:1 train brake integrated test-bed is taken as the research object, and the test methods of the characteristic parameters related to the adhesive characteristics under the brak-ing condition are analyzed in detail, including the slip ratio, adhesive force and positive pressure. Finally, the test-bed was used to carry out the repeated test under the same working condition, and the relationship between the adhesion coefficient and slip ratio was obtained through data sorting and analysis. It was confirmed that the 1:1 train brake integrated test-bed can meet the test of the adhesion coefficient between the wheel and rail during the braking process.
