An Analysis of the Reliability of Safety Space between Metro Vehicle Gauge and Equipment Gauge |
| |
| Abstract: | 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. |
