Comparative Analysis of Balanced Maintenance System and Scheduled Maintenance System for Urban Rail Transit Vehicle

Journal Title: Urban Mass Transit - Year 2024, Vol 27, Issue 3

Abstract

[Objective] In order to reduce the purchase cost and operation and maintenance cost of urban rail transit vehicles as much as possible, balanced maintenance system is adopted in some cities in China. Therefore, it is necessary to make comparative analysis on the balanced maintenance system and the traditional scheduled maintenance system. [Method] With the urban rail transit in Chongqing as an example, the maintenance process and maintenance cycle under two maintenance systems are introduced respectively, and the vehicle online rate and maintenance position amount under two maintenance systems are compared and analyzed. [Result & Conclusion] Compared with the traditional scheduled maintenance system, the annual detention time of each train under the balanced maintenance system is reduced by 19 days, and the number of required maintenance position is increased by 18.5%. The result shows that the balanced maintenance system for urban rail transit vehicles is more reasonable.
