地铁车辆限界与设备限界间安全裕量的可靠性再分析——地铁列车与屏蔽门间隙测试

Reanalysis of the Reliability of Safety Space between Metro Vehicle Gauge and Equipment Gauge——A Test on the Gap between Train and Platform Screen Door

根据地铁限界标准,列车与屏蔽门之间必须保留一定间隙,以保证列车在规定条件下能安全通过该设备区域。乘客上下车安全与行车设备安全同样是地铁运营中的核心问题。实际测试了地铁列车进出车站和通过车站时与屏蔽门间的动态间隙,在正态分布假设下对试验数据进行了拟合,预计了车辆随机晃动下与屏蔽门间的间隙值,从乘客上下车安全角度对现行的地铁车辆限界与设备限界间的安全裕量值进行再评估,为将来地铁车站屏蔽门设计及站台设备安装提供参考。

According to the Bostrab Standards,a certain gap must be kept between train and PSD to ensure the safty of a passing train.In the operation of metro system,the safety of passengers going up and down the train is an issue as important as the safety of traffic equipments.Through a test of the dynamic gap between PSD and trains that pulled in or out station and from the angle of passengers＇ movement,this paper obtains the experimental data and estimates the gap with random shaking of vehicles.This formula,the authors argue,will be a good reference for PSD design and platform equipments installation.
