利用弹性线夹优化刚性接触网的动态性能

Optimization of Dynamic Performance on Rigid Catenary by Using Flexible Clamp

架空刚性接触网以其安装净空低、无断线隐患及维护工作量少等特点;被广泛地应用于隧道内的电气化铁路和城市轨道交通中。研究了弹性线夹对刚性接触网动态性能的影响。通过有限元法,推导受电弓-刚性接触网动力学模型。根据弓网接触质量的评价标准,得出刚性接触网采用弹性线夹能够得到弓网的最优动态性能。

Overhead rigid catenary is widely used in main railway lines and urban rail transit because of the low installation clearance,low breakage risks and less maintain works.The influence of flexible clamp over the dynamic performance of the overhead rigid catenary is studied,by using the finite element method,a dynamical model of pantograph-catenary is derived.According to the pantograph-catenary evaluation criteria,if the pesitioning clamps are replaced by flexible clamps,the best dynamic performance will be achieved.
