大规模动车组高级修工艺设计研究

Research on Advanced Maintenance Technology Design for Large-scale EMUs

动车段承担动车组高级修作业,检修工艺复杂,合理的工艺设计是实现检修功能、检修能力和检修效率的重要因素。大规模动车组高级修工程设计关键技术是解决检修工艺的"完整性、可靠性、故障安全性、均衡性、通畅性"等问题。文章以成都动车段高级修为案例,通过调研现场生产情况、分析检修工艺技术,并结合国内工艺设计成果,最终采用功能分区、缩短流水线、双检修线、工序法等方法,有效的解决了问题。研究结果可为开展动车组高级修工艺设计提供参考。

The EMU Depot undertakes the advanced repair work of the EMUs.As the maintenance technology is complex,the reasonable technology design is an important factor to realize the maintenance function,the maintenance ability and the maintenance efficiency.The key technology of advanced maintenance work design for large-scale EMUs is used to solve"integrity,reliability,fault security,balance,smoothness"of maintenance technology.Taking advanced maintenance of Chengdu EMU Depot as an example,by investigating the on-site production situation,analyzing the maintenance technology and being combined with the domestic technology design results,such methods as functional zoning method,assembly line shortening,double maintenance line and process method the above problems have been adopted to effectively solved the above problems.The research results can provide the references for the advanced maintenance technology design of the EMUs.
