摘要和关键词

摘要: 为提高高速弓网耦合系统动力学性能,文章以DSA380型高速受电弓和大西线高速铁路弹性链式悬挂接触网系统为研究对象,利用有限元法建立弓网耦合系统动力学模型;基于遗传算法理论和弓网系统动态仿真平台,依次研究受电弓三参数联合变化对单、双受电弓与接触网系统间动力学性能的影响,并根据弓网系统动态性能评价标准对受电弓三参数进行优化,得到高速受电弓三参数最佳匹配组合,给出了适用于高速情况下的单、双受电弓设计优化方案。研究结果表明,相较于DSA380型受电弓原设计方案,单、双受电弓设计优化方案均有效地提升了单、双受电弓受流情况下的弓网耦合系统动力学性能。研究成果可为高速受电弓结构参数设计提供参考和建议。

Abstract and Keywords

Abstract: In order to improve the dynamic performance of high-speed pantograph-catenary coupling system, this paper takes DSA380 high-speed pantograph and elastic chain suspension catenary system of Datong-Xi'an high-speed railway as research objects, and establishes the dynamic model of pantograph-catenary coupling system by the finite element method. Based on the genetic algorithm theory and the dynamic simulation platform of pantograph-catenary system, the influence of joint changes of three parameters of pantograph on the dynamic performance between single/double pantograph and catenary system is studied in turn. According to the dynamic performance evaluation standard of pantograph-catenary system, the optimization of three parameters of pantograph is carried out, the best matching combination of three parameters is obtained, and the design optimization scheme of single and double pantograph is presented. The research results show that, compared with the original design scheme of DSA380 pantograph, the design optimization scheme of single and double pantograph can effectively improve the dynamic performance of pantograph-catenary coupling system under the condition of single and double pantograph current collection. The research achievements can provide reference and suggestions for structural parameter design of high-speed pantograph.

Keywords: pantograph-catenary interaction; double-pantograph operation; dynamic simulation; genetic algorithm; parameter optimization
