铁路枢纽内动车组运维检修规模测算分析研究

Analysis and Research on the Scale of Operation Maintenance and Repair of EMUs in Railway Hub

鉴于在新建高速铁路枢纽内动车组配属、承担动车段(所)动车组检修工作量及检修设施规模测算结果中表现出不统一、不协调及不匹配等问题,提出以列车运行图、全周转时间及日车公里法为指标的3种枢纽内动车组配属规模测算方法,重点研究以动车组日车公里及全周转时间为主要指标,测算枢纽内动车组配属规模,同时给出承担动车段(所)动车组检修工作量及检修设施规模测算方法。研究结果表明采用动车组日车公里指标测算结果裕量较大,需结合枢纽内铁路主要技术标准、客流及行车方案等合理调整枢纽内动车组平均日走形公里指标,但该测算方法分析计算较为方便,适合应用于远期铁路枢纽规划投资及动车组车辆投产规模控制等方面。采用动车组全周转时间指标测算结果较为科学合理,能有效提高动车组使用率及运转率,同时在运维检修方面可有效降低检修资源的浪费,减少工程建设投资。

In view of the inconsistency and incompatibility in the calculation results of the EMU assignment,the undertaking of the EMU maintenance workload of the EMU depot(station),and the scale of the maintenance facilities in the newly built high-speed railway hub,this article proposes,Three methods for measuring the size of the EMUs in the hub using the full turnaround time and daily train-kilometer method as indicators.Focusing on the daily EMU-kilometres and full turnaround time as the main indicators to calculate the size of the EMUs in the hub,it explores the overhaul workload of the EMU depot(station)and the method for calculating the scale of overhaul facilities.The research results show that the calculation results using the daily train-kilometer index of EMUs have a large margin,and it is necessary to rationally adjust the average daily shape-kilometer indicators of the EMUs in the hub based on the main technical standards of the railway in the hub,passenger flow,and driving plan.However,the calculation method is more convenient and suitable for long-term railway hub planning investment and EMU vehicle production scale control.The calculation results using the full turnaround time index of EMUs are more scientific and reasonable,which can effectively improve the utilization rate and operation rate of EMUs.At the same time,it can effectively reduce the waste of maintenance resources and the investment in engineering construction in terms of operation and maintenance.
