摘要
目前我国已形成了350 km/h高速铁路的成套技术体系,但该技术体系对400 km/h高速铁路的适用性需要重新评估。在高速铁路中,受电弓-接触网系统是列车的唯一供能系统,也是决定高速铁路列车运行速度的关键因素。目前,国内外尚无400 km/h线路开通运行,其理论研究需在充分总结350 km/h研究成果的基础上开展。本文对400 km/h高速铁路接触网系统进行了数值仿真研究分析,并提出了400 km/h高速铁路接触网系统的研究展望:(1)总结目前350 km/h高速铁路接触网系统技术的研究成果与短板;(2)分析仿真方法对400 km/h高速铁路接触网系统的适应性;(3)研讨400 km/h接触网系统动态性能指标的确定方案。
At present,China has formed a complete technical system for 350km/h high-speed railway,but the applicability of the technical system to 400 km/h high-speed railways needs to be re-evaluated.In high-speed railway,the pantograph-catenary system is the only energy supply system for trains,and also the key factor to determine the operation speed of high-speed railway trains.At present,no 400 km/h track has been put into operation at home and abroad,so the theoretical research should be carried out on the basis of fully summarizing the research results of 350 km/h high-speed railways.In this paper,the overhead contact system of 400 km/h high-speed railway is studied and analyzed by numerical simulation,and the research prospect for overhead contact system of 400 km/h high-speed railway is put forward:(1)Summarize the existing research results and shortcomings of overhead contact system technology of 350 km/h high-speed railway.(2)Analyze the adaptability of simulation method to overhead contact system of 400 km/h high-speed railway.(3)Discuss the scheme of determining the dynamic performance indicators of overhead contact system of 400 km/h high-speed railway.
