摘要
针对轨道交通供电系统钢轨与回流电缆连接存在的问题,对不同连接工艺制作的钢轨样品连接点处的机械性能、电气性能进行有限元模拟分析和试验;根据对试验数据的系统研究和分析结果,确定合理的连接工艺,以消除地铁运营的安全隐患。
In view of the existing problems in the connection of power supply rail and backflow electric cables, finite element simulation analysis and tests were carried out for the mechanical and electrical properties at the junction points of the sample track manufactured by different connection crafts. Test result data were systematically analyzed to determine the reasonable connection craft to eliminate metro operation hidden risks.
