摘　　要：论述了列车常用制动限速的概念、决定因素和解算方法。重点指出对闸瓦摩擦系数带有初速修正项和不带初速修正项的常用制动限速计算方法的不同点 ,在解算常用制动限速问题时常用制动系数取为 0 7是合理的。给出了常用制动限速表 ,指明了常用制动限速的应用范围和注意事项。This paper elaborated the concept,the determining factor and calculation method of train common brake speed limiting.It pointed out common brake speed limiting computational method difference between using the initial speed correction and not using the initial speed correction about the brake shoe friction coefficient.It also point out that it was reasonable that the common brake ratio took 0.7 when the problem of common brake speed limiting was calculated.It gave out the common brake speed limiting table,and indicated the common brake speed limiting application scope.

关 键 词：常用制动 限速 解算方法 应用
