高速受电弓作用下接触网整体吊弦动态力研究
Study on Dynamic Force of Integral Dropper of Catenary under Action of High-Speed Pantograph
摘要
Abstract
The catenary of elastic chain type widely used at present for high speed railway in China was taken as the research object.The dynamic uplift of integral droppers obtained from field tests was used as the initial load of finite element simulation.The installation and construction process of the messenger wire,the contact line and integral droppers was simulated with the finite element model of catenary established by ANSYS software.Based on simulation results,the form-finding analysis and transient dynamics analysis for the catenary were analysed,and the changes of tension,compression and dynamic force of integral dropper under the action of pantograph were studied.Results show that the dynamic force of the integral dropper fluctuates greatly,which is about 6 times of its static force when the pantograph passes through.In the same span,the largest force fluctuations occur on number 1 and 5 integral droppersand with the maximum amplitude of compression.The compression frequency of number 3 integral dropper is the maximum.关键词
