随着多条客运专线的开通,国内高速动车组服役环境变得日益复杂,对动车组运行安全性和可靠性带来了新的挑战。为研究高速动车组在复杂服役环境下的服役性能,选取CRH3系列动车组在武广、京广和京沪客运专线进行长期服役性能跟踪,获取了动车组运营条件下服役环境、服役状态和服役性能的大量数据并进行了关联分析,得到了高速动车组服役性能随运用环境和服役状态的变化规律,为高速动车组的研发设计和运用维护提供依据和参考。 With the opening of a number of passenger dedicated lines, the service environment of domestic high-speed EMUs has become increasingly complicated, posing new challenges to the operational safety and reliability of EMUs. In order to study the service performance of high-speed EMU in complex service environment, the long-term service performance of CRH3 EMU was selected to be tracked in Wuhan-Guangzhou, Beijing-Guangzhou and Beijing-Shanghai passenger dedicated lines, and the service environment, service status and service A large amount of data of performance and a correlation analysis have been obtained, the high-speed EMU service performance with the use of the environment and service status of the law of change for the high-speed EMU R & D design and application provide the basis and reference.
