【摘要】 吊弦是链型悬挂接触网的重要组成部分,其布置对受电弓接触网系统受流性能有重要的影响。针对接触网故障中的吊弦失效,基于ANSYS软件平台建立了含吊弦失效的接触网有限元模型;受电弓采用归算质量模型;通过直接积分法对弓网系统相互作用进行仿真计算。对比分析吊弦失效对弓网受流性能的影响,得出吊线失效影响力与运行速度有关,且只在局部范围内有影响。同时对比单双弓计算结果得出吊线失效对单双弓影响规律相同的结论。更多还原

【Abstract】 The hanging string is an important part of catenary suspension catenary,and its arrangement has an important influence on the current performance of the pantograph catenary system.Based on ANSYS,a finite element model of catenary with suspension string failure is established for the failure of catenary in catenary fault.The pantograph adopts the reduced mass model.The interaction of the pantograph/catenary system is simulated by direct integration method.The influence of suspension string failure on the current performance of the pantograph/catenary is compared and analyzed.It is concluded that the influence of suspension line failure is related to the running speed,and only affects in a certain area.At the same time,the results of the single-double-bow calculation show that the effect of suspension line on single and double bow is the same.更多还原
