城市轨道交通车辆与铁路干线车辆制动适应性研究

Adaptability of Brake System for Metro Vehicles and Main Line Trains

通过对城市轨道交通车辆直通制动机与铁路干线货物列车自动制动机两种制动机制动指令的转换,及制动上升率、制动量和制动起始点的确定等适应性研究,解决两种制动机之间的制动指令的识别和制动性能的匹配。即采用直通制动机的城市轨道交通车辆能识别并执行干线铁路机车车辆所发出的制动指令,并使城市轨道交通车辆的制动加速度和铁路货物列车的加速度基本保持一致,从而实现城市轨道交通车辆通过联挂于铁路干线货物列车进行运输。

Based on a research of the conversion of brake command, the confirmation of braking increase rate, the braking capacity, the braking point of the straight brake in metro vehicles and the automatic brake of main line trains, this paper attempts to solve the matching problem between brake command classification and brake performance of two brake systems, that means metro vehicles can receive and execute the command sent by main line trains, and keep the braking retardation of metro vehicles consistent with the retardation of goods trains. So the metro vehicles can interact basically with the main line trains.
