Adaptability Analysis of Suspended Structure of Overhead Contact Line in Wind Areas along Lanzhou-Urumqi High Speed Railway
摘要
Abstract
Experiments and operational experiences show that the fatigue wear problem of catenary feeder is very prominent in wind areas along Lanzhou Urumqi High-Speed Railway. In this paper,based on the combination of theoretical and practical methods and the finite element method of three-dimensional fluid field,the characteristics of wind movement behind the wind wall and the movement characteristics of AF line influenced by wind wall structure are analyzed in terms of a hundred-mile and a thirty-mile wind areas,and the mechanism of large amplitude vibration caused by excitation source interference of AF line is proposed. In accordance with the sample spatial data and the motion frequency of AF line's V type suspension articulated components,key points in rational design of AF line's V type suspension structure and the importance of structure matching are put forward,and effective measures are listed to limit wear between components.关键词
