城市轨道交通救援连挂列车的制动距离计算及临界速度研究

Braking Distanceand Critical Velocity Calculation of Rescue Coupled Trains in Urban Rail Transit

分析了城市轨道交通救援连挂列车制动距离的计算方法。从车辆设备的角度,分析了救援连挂列车制动距离计算的基本特点,并通过某型救援连挂列车紧急制动距离的计算实例,分析了救援连挂列车推行临界速度确定的基本原则和计算方法,为提高救援连挂列车的救援效率提供辅助决策信息。

The braking distance calculation of urban railway rescue coupled trains is introduced. In terms of vehicle equip- ment, the primary characteristics of train braking distance com- puting are analyzed. Then through a calculation instance of e- mergency braking distance of a certain type rescue coupled train, the primary principle and calculation method of the res- cue coupled train＇s critical velocity are also analyzed. This re- search will help to improve the rescue efficiency of rescue cou- pled trains and the decision-making information.
