摘　　要：成都地铁18号线首次采用改造后的市域A型车,运行速度为140km/h,其大架修模式尚无可参考借鉴案例。考虑其运行速度高、线路长、站点少和运营里程累积快等特点,若遵循《成都市域快速轨道交通工程设计规范》要求,将造成过度修情况,增加不必要的运营维护成本。因此,本研究根据动力学理论开展结构可靠性和关键部件检修标准评估。以此为基础,在保证车辆运营安全的前提下,以降低运营成本、提高经济效益为目标,科学合理地开展成都地铁18号线市域快速车辆修程修制优化研究,探索出适用于车辆的大架修修程模式。实践证明,该模式在确保运营安全的基础上创造出巨大的经济效益,为其他市域快线列车大架修模式提供参考。This marks the first time that a renovated urban A-type train with an operating speed of 140 km/h has been deployed on Chengdu metro line 18.Therefore,there is no reference case for its intermediate and overhaul maintenance.Considering its high operating speed,longer route,fewer stations,and fast operating mileage,following the requirements of the Code for Engineering Design of Chengdu Urban Region Rapid Rail Transit will result in over-maintenance and increase unnecessary operation and maintenance costs.Therefore,based on the theory of dynamics,this study evaluates the structural reliability and key component maintenance standards.Based on this,with the goal of reducing operating costs and improving economic benefits,this study optimizes the urban rapid vehicle maintenance system of Chengdu metro line 18in a scientific and reasonable manner while ensuring the safety of vehicle operations.In addition,this study explores a class of maintenance systems for intermediate and overhaul maintenance that is suitable for this type of vehicle.Practice has proven that this model creates huge economic benefits based on operational safety,providing a reference for other urban express train intermediates and overhaul maintenance operations.
