摘要:
［目的］大架修作业是城市轨道交通车辆检修工作组织的难点与瓶颈点，目前尚缺乏对大架修作业内容的梳理及面向维修优化的工艺设计。［方法］分析和改进城市轨道交通车辆高级修程的工艺设计，以提高检修作业安排的合理性，有效应对因线网里程增加和客流规模增大产生的检修工作需求。基于既有研究中关于维修设施布局和维修任务顺序优化的成果，分析城市轨道交通车辆的大架修现状，归纳了大架修作业中线路间移位修、部件集中专项修、检修策略多样等特点，之后从工艺流程、检修策略和维修资源配置角度梳理了大架修的工艺特点。进一步提出了大架修的灵活工艺，包括在工艺流程中增加并行作业、根据检修线作业能力调整检修策略、在维修资源配置中分离维修设备和人员。以城市轨道交通6编组列车实际架修流程进行算例分析。［结果及结论］在固定工艺流程下采取同步检修策略所需检修时间为25.0 d，应用灵活工艺的检修所需时间仅为17.5 d，相比固定工艺可减少7.5 d的检修时间。检修时间的减少来自于并行作业的引入和在维修设施能力不足的情况下避免执行车辆整体同步检修策略。算例结果表明，应用灵活工艺可有效缩短列车的大架修作业时间，提高城市轨道交通车辆的维修效率。
Abstracts:
［Objective］ Overhaul operations for urban rail transit vehicles pose challenges and bottlenecks in the organization of maintenance work. Currently, there is a lack of systematic exploration of the overhaul contents and process design tailored for maintenance. ［Method］ Analyzing and refining the process design for the advanced overhaul schedule of urban rail transit vehicles is essential to improving the rationality of maintenance work arrangement, and effectively address the increased maintenance work demands resulting from the expansion of line network mileage and passenger flow volume. Based on existing research achievements regarding maintenance facility layout and maintenance task sequence optimization, the current urban rail transit vehicle overhaul situation is analyzed. Features such as shift repairs between lines, concentrated component-specific repairs, and diverse maintenance strategies in the overhaul operations are summarized. Subsequently, the process characteristics of the overhaul are outlined from the perspectives of process flow, maintenance strategies, and allocation of maintenance resources. Furthermore, a flexible process for overhaul is proposed, including the introduction of parallel operations in the process flow, adjustment of maintenance strategies based on the operational capacity of the maintenance line, and the separation of maintenance equipment and personnel in the allocation of maintenance resources. A computational example analysis is carried out based on the actual overhaul process of a 6-car formation urban rail transit train. ［Result & Conclusion］ Under a fixed process flow, the overhaul time required for synchronous maintenance strategy is 25 days. By applying flexible process, the required maintenance time is reduced to only 17.5 days, resulting in a 7.5-day reduction in maintenance time compared to the fixed process. The reduction in maintenance time stems from the introduction of parallel operations and the avoidance of executing synchronous overhaul strategy for the entire vehicle when the maintenance facility capacity is insufficient. The computational example results indicate that applying flexible process can effectively shorten the overhaul time of trains, thereby enhancing the maintenance efficiency of urban rail transit vehicles.
