高速列车服役性能研究

Study on high-speed train service performance

高速列车运行时空上的跨越所面临的振动、环境变化,使其服役状态与安全性态始终处于时变状态,给高速列车安全保障与健康维护带来极大的挑战。随着高速列车运营里程的增长,高速列车服役性能的研究成为保障我国高速列车技术持续发展的重要课题。在分析高速列车服役性能基本内容的基础上,提出了高速列车服役性能检测体系,阐明了其建设内容与方案,并发展了高速列车走行部跟踪试验技术,跟踪试验对高速列车服役性能的研究具有显著成效与提升。最后,指出了本领域今后的发展趋势及需重点关注与加强的研究工作。

Due to the space-timespan, there always is variation on the vibration and climate, which makes the service status and safety state of high-speed trains remain the time-varying, and at the same time it brings huge challenges to high-speed train security assurance and health maintenance. As the growth of the high-speed train operation mileage, studying on the service performance of high-speed train become an important topic as a guarantee for sustainable devel- opment of China＇ s high-speed train technology. Based on the content analysis of the high-speed train service performance, the high-speed train service performance testing system is present- ed, and its construction content and scheme is expounded. On this basis, the high-speed train tracking test technology is developed, which has significant efficiency and promotion for the studying on service performance of high-speed train. Finally, the development trend and strengthen research work of this study field in the future is indicated.
