摘要:
［目的］市域轨道交通车辆是为了适配市域轨道交通线路而全新设计开发的车型，其使用环境、线路参数及车辆配置同高速铁路动车组、城市轨道交通车辆相比均有所区别。有必要对市域轨道交通车辆的修程模式开展研究。［方法］从平衡车辆的可靠性和经济性角度出发，提出了适合市域轨道交通车辆的修程模式。对比分析了相关标准对市域轨道交通车辆修程的要求，并将这些要求作为制定其修程模式的首要参考条件。调研了我国已投入运营的4条市域轨道交通线路的车辆运用情况，获得这些线路实际的车辆修程数据。以其中的2条线路为例，对实际线路的RAMS(可靠性、可用性、可维护性和安全性)数据与零部件寿命的匹配性进行分析，从安全性、经济性和设备寿命匹配等角度，对车辆修程制度进行了综合衡量。［结果及结论］市域轨道交通车辆修程的制定，须同时考虑零部件使用寿命的2个强相关因素——运用时间和运用里程，并选取二者匹配性最优的修程模式。市域轨道交通车辆日常运用修分为2个级别：列检(一级修)、以运用时间或运用里程为考量指标的月检(二级修)。高级修则分为定修-架修-大修系列，或分为三级修-四级修-五级修系列。
Abstracts:
［Objective］ City rail transit vehicles are specifically designed and developed models to adapt to city rail transit lines, differing in operational environment, line parameters, and vehicle configurations from high-speed railway EMU and urban rail transit vehicles. It is essential to conduct research on the maintenance mode for city rail transit vehicles. ［Method］ From the perspective of balancing vehicle reliability and economic efficiency, a suitable maintenance mode for city rail transit vehicles is proposed. The requirements for city rail transit vehicle maintenance from relevant standards are compared and analyzed, using these standards as the primary reference for the maintenance mode formulation. The operational status of vehicles on four launched city rail transit lines in China is surveyed to obtain actual vehicle maintenance data. Two of these lines are selected as examples for analyzing the compatibility of their actual RAMS (reliability, availability, maintainability, and safety) data with component lifespans. The vehicle maintenance system is comprehensively evaluated from the perspectives of safety, economic efficiency, and equipment lifespan compatibility. ［Result & Conclusion］ The formulation of maintenance schedules for city rail transit vehicle must consider two key factors closely related to component lifespans: operating time and mileage. The maintenance mode with optimal compatibility between these two factors should be selected. Routine operational maintenance of city rail transit vehicle is divided into two levels: train inspection (Level 1) and monthly inspection (Level 2), which uses operating time or mileage as assessment indicators. The advanced maintenance mode is categorized into a series of schedule maintenance, medium and major overhauls, or into a Level 3, Level 4, and Level 5 maintenance series.
