市域铁路潮汐客流下车辆检修模式和规模研究

Research on Mode and Scale of Rolling Stock Inspection and Maintenance under Tidal Passenger Flow of Urban Railway

市域铁路全日客流不均衡特性突出,潮汐客流显著,平峰时段列车下线到晚高峰前上线接续时间长,下线列车数量占比大。结合上述特点可考虑日班开展检修工作,需研究市域铁路潮汐客流特征下车辆基地检修模式和规模。提出市域铁路车辆均衡修整数线性规划模型,完成利用交路接续间隔时间检修的工艺模拟仿真计算,提出潮汐客流特征下车辆基地规模计算方法,完成2种车辆检修模式适应性分析。

The all-day passenger flow of urban railways is prominently unbalanced,the tidal passenger flow is significant,there is a long duration from withdrawing trains from operation in off-peak hours to continuing operation before the evening peak,and the number of trains withdrawn from operation accounts for a greater proportion.The inspection and maintenance can be carried out in daily shift according to the above characteristics,so it is necessary to study the maintenance mode and scale of rolling stock base under the characteristics of tidal passenger flow of urban railway.A linear integer programming model for balanced maintenance of urban railway rolling stock is proposed to complete the process simulation calculation of inspection and maintenance utilizing interval time of routing continuation,and a calculation method of rolling stock base scale under the characteristics of tidal passenger flow is proposed to complete the adaptability analysis of two inspection and maintenance modes of rolling stock.
