Abstract: This paper introduces the RAMS management strategy, and analyzes the reliability of various key components of the onboard signaling subsystem. The fault statistics of equipment components are used as the basic data, and calculation model establishment is taken as the analysis method, to analyze the equipment fault modes and their hazards, thereby assessing the existing maintenance mode. This research provides reference for the improvement of maintenance procedures for onboard signaling equipment, to ultimately achieve the goal of improving the operational stability of onboard signaling equipment.

Key words: RAMS, onboard system, fault statistics, maintenance procedure improvement

摘要: 通过介绍RAMS管理策略,分析信号车载子系统各关键设备的可靠性,以设备部件的故障统计为基础数据,以建立测算模型为分析手段,对设备的故障模式及危害性进行分析,从而对现行维护模式进行评估,为信号车载设备修程修制优化提供参考基础,最终达到提升信号车载设备运行稳定性的目的。
