摘要:
从地铁列车空转打滑的现象出发，基于力学模型，简述了空转打滑常用的判定方法和信号系统对其的处理措施。对加、减速时列车的定位误差进行了分析，采用 Matlab软件分析了列车空转打滑时打滑率和紧急保障制动率对行车的影响。结果表明，通过地铁信号系统准确判定空转打滑并调整保障制动率，可以达到合理控车的目标。
Abstracts:
Starting from the phenomenon of metro train idling and sliding, based on mechanical model, the common idling-sliding determination methods and the processing measures of the signaling system are described. The positioning error of the train during acceleration and deceleration is analyzed, and Matlab software is used to analyze the influence of the sliding rate and emergency guarantee braking rate on train running when the train is idling and sidling. The results demonstrate that, by metro signaling system accurately determining idling/sliding and adjusting guarantee braking rate, the goal of reasonable train control can be obtained.
