摘要
接触网系统作为高速铁路牵引供电系统的关键组成部分,对于高铁动车组的正常运行至关重要。历次地震灾害表明,接触网系统容易受到地震作用而发生不同程度的破坏。从4个方面系统梳理了接触网的地震研究进展:探讨接触网的动力学建模及其固有动力特性,分析接触网在地震中的震害特点及常见破坏类型,回顾接触网的地震响应研究及其影响因素,综述接触网抗震研究的现状;并对比分析了不同国家和地区在接触网抗震设计标准规范方面的异同。通过梳理相关研究现状,对未来研究方向进行展望。
The catenary system,which is regarded as a critical component of the high-speed rail traction power supply system,is deemed essential for the normal operation of high-speed trains.It has been demonstrated by previous earthquake disasters that the catenary system is susceptible to varying degrees of damage under seismic effects.The seismic research progress of the catenary system was systematically reviewed from four aspects:the dynamics modeling and inherent dynamic characteristics of the catenary system,the seismic damage characteristics and common types of failures,the seismic response of the catenary system and its influencing factors,and an overview of the current state of earthquake resistance research,which includes a comparative analysis of the seismic design standards and regulations for catenary systems in different countries and regions.By summarizing the relevant research,prospects for future research directions are provided.
