摘要

通过计算分析，阐述了车轮保持制动过程中不产生滑行的条件，货物列车制动率的选取以及列车最高运行速度、紧急制动距离限值、制动率和轴重间的关系。阐明了轴重提高到25～30 t后，制动距离限值不延长，必须降低列车最高运行速度；要保证货物列车最高运行速度，必须延长制动距离限值。

Abstract

Based on calculation and analysis, the conditions of wheel keeping from sliding in brake, selection of freight train brake rating, and relations between train axle, the highest running speed, distance limit of emergency brake, and brake rating were expounded. It was pointed that the train highest running speed must be reduced when the axle load was increased to 25~30 t without extending brake distance limit, on the other hand, the train brake distance limit must be extending to keep the highest running speed.
