摘要
牵引系统的可靠性对于地铁车辆的安全运行极为重要。文章结合某地铁线路的现场车辆检修记录,采用故障树法和蒙特卡洛法分析牵引系统的可靠性。首先,根据现场检修数据建立地铁牵引系统的故障树模型,并对所建立的故障树模型进行定性、定量分析。其次,运用蒙特卡洛法对地铁牵引系统进行可靠性仿真。最后,确定了牵引系统的薄弱环节和各部件的重要度,对地铁列车的可靠性设计和制定检修策略具有重要借鉴意义。
The reliability of traction system is very important for the safe operation of metro vehicles.This paper analyzes the reliability of traction system by Fault Tree method and Monte Carlo method based on the field fault maintenance record of a subway line.Firstly,the fault tree model of subway traction system is established according to the on-site maintenance data,and the fault tree model is analyzed qualitatively and quantitatively.Secondly,Monte Carlo method is used to simulate the reliability of subway traction system.Finally,the weak links of traction system and the importance of each component are determined,which has important reference significance for reliability design and maintenance strategy of metro train.
