中国高速动车组运用检修状况与发展

Development and State of Operation and Maintenance for China High-speed Trains

从动车组车型特征、运用特点、修程修制等方面介绍了中国高速动车组运用及检修现状;针对快速发展的动车组运营需求,从日走行里程、检修效率、检修成本等方面分析了动车组运用与检修所面临的挑战;结合近年来检修和运用实践,从检修规程优化、检修周期延长、检修方式调整等方面综述了动车组运用检修优化进展和成果。实践表明,中国高速动车组运营更加高效、经济,检修质量更趋稳定、可控。

The state of operation and maintenance for china high speed trains were introdued from properties、operational characteristics、maintenance procedure and system of EMU.In view of the rapid development of the EMU operational demands,the challenges of operation and maintenance were analysed from daily running mileage、maintenance efficiency and maintenance cost.According to the recent practice of EMU operation and maintenance,optimization results and progress were sumed up from maintenance procedure optimization、maintenance cycle extend and maintenance mode adjustment.Application showed that China high speed trains operation is more efficient and economic,and the quality of maintenance is more stable and controllable.
