摘要
车辆限界与设备限界间安全裕量对地铁列车安全运营有直接影响。根据高斯误差传播理论 ,推导出服从正态分布的累计误差计算公式 ,确定不同可靠度下地铁车辆限界与设备限界间安全裕量的取值 ,为地铁车辆轮廓线设计。
The safety space between metro vehicle gauge and equipment gauge is a direct factor to influence train operation.According to Gauss Error Propagation theory,this paper leads to a formula for the accumulative error calculation obeying normal distribution,which is used to analyze random key factors' proportion in metro vehicle gauge and define the values of safety space between metro vehicle gauge and equipment gauge under different reliable conditions.This formula,the authors argue,will be a good reference for the design,check and delivery as well as installation of metro vehicles and tunnel equipment.
