摘要:
［目的］站台门作为乘客上下车的重要通道，对乘客的安全出行起着至关重要的作用。为确保站台门系统的安全稳定运行，基于故障数据对站台门系统进行可靠性分析，并依据分析结果对其维保策略进行优化调整。［方法］基于天津某地铁运营线路2018—2021年地铁车站站台门的故障数据，结合站台门系统的结构和功能，对站台门系统的常见故障进行分类统计。采用数理统计、故障分布拟合等方法确定系统可靠度函数，在可靠度约束下构建以设备平均维修费用最小为目标的维修周期优化模型，优化站台门系统维保策略。［结果及结论］根据故障数据拟合结果，站台门机械系统和电气系统的故障分布均服从Weibull分布。在现有设备运行状态下，站台门机械系统的最佳维修周期为20 d，电气系统的最佳维修周期为7 d。站台门系统的维保策略可以调整为整体实施三周检，电气系统实施周检。
Abstracts:
［Objective］As an important passage for passengers to get on and off the train, the platform screen door (PSD) plays a crucial role in passenger safety. To ensure the safe and stable operation of the PSD system, a reliability analysis of this system is carried out based on fault data, and its mai-ntenance strategy is optimized and adjusted as per analysis results. ［Method］Based on the fault data of subway station PSD of a certain Tianjin subway line from 2018 to 2021, and combined with the structure and function of the PSD system, common failures of the PSD system are classified and counted. The system reliability function is determined through methods like mathematical statistics and fault distribution fitting. With the goal of minimizing the equipment average maintenance cost, a maintenance cycle optimization model is constructed under reliability constraints to optimize the PSD system maintenance strategy. ［Result & Conclusion］According to fault data fitting results, the fault distribution of both the PSD mechanical system and the electrical system obey the Weibull distribution. Under the existing equipment operation status, the optimal maintenance cycle of the PSD mechanical system is 20 days, and that of the electrical system is 7 days. Therefore, the PSD system maintenance strategy can be adjusted to a three-week whole system inspection with weekly electrical system inspections.
