摘要/Abstract

摘要： 为解决兰新高铁大风区段接触网正馈线在大风天气下发生剧烈舞动问题及线夹运动致金具磨损问题,提出一种减档距防舞器。建立正馈线有限元模型,施以导线自重荷载及风速22.14 m/s(9级风)的气动荷载,获得安装减档距绝缘子前后正馈线舞动响应。分析表明,9级风速下,未安装防舞器前,正馈线舞动强劲,垂直、水平位移峰值分别为3.061、2.468 m;安装减档距长度3.0 m的防舞器后,导线舞动抑制效果最佳,垂直、水平位移峰值分别为1.940、1.541 m,分别降低36.62%、37.56%,安装后的正馈线最大张力由113.042 kN降至导线设计破坏张力之下,张力波动减小。线夹运动最大磨损角从40.53°降至防舞器安装后的8.23°。研究结果表明,减档距长度3.0 m的防舞器能够有效抑制导线舞动,减小线夹运动磨损。
