摘要

电气化铁路接触网在风载荷的作用下会产生风偏和振动，纵向风偏会导致接触线和受电弓受流质量降低，引发接触力波动增大、受电弓离线等故障。横向风偏会增加受电弓滑板的接触区域，严重时引发接触线横向脱线，导致刮弓事故。文章针对强风地区接触网的风偏特性进行深入研究，并提出基于非线性有限元的接触网风偏计算方法，为接触网设计和风偏预防提供指导。具体方法为：考虑接触线截面形状不规则，在Fluent中构建接触线截面的流体力学计算模型，通过绕流仿真获得不同风攻角下的接触线气动力系数；基于流体诱发振动理论，推导作用在接触线与承力索的静风载荷模型；充分考虑风偏发生时的接触网几何非线性，基于绝对节点坐标法推导接触网整体刚度矩阵，并建立了接触网三维非线性有限元模型；通过施加风载荷求解得到了接触线在不同风速和不同初始风攻角的静风载荷作用下产生的风偏。以实际接触网数据为算例，计算结果表明：在不同风速和初始风攻角下，接触网受静风载荷作用产生的接触线风偏受到其气动力系数的影响，且随风速增加而增大，对风攻角也很敏感。当风速达到30 m/s时，接触网横向最大风偏可达到受电弓滑板日常工作长度的8.3%，容易导致刮弓事故的发生。

Abstract

The electrified railway catenary generates wind deflection and vibration under wind load. The longitudinal wind deflection affects the current collection quality of the contact wire and the pantograph

and causes contact force fluctuations and pantograph-catenary separation fault. The lateral wind deflection increases the contact area of the pantograph’s sliding strip

and in severe cases

the contact line is off-line laterally

resulting in pantograph scraping accidents. This paper conducted an in-depth research on the wind deflection characteristics of catenary systems in strong wind areas

and proposed a calculation method for catenary wind deflection based on nonlinear finite element to provide guidance for catenary design and wind deflection prevention. The specific methods are as follows: Considering the irregular shape of the contact wire cross-section

a hydrodynamic calculation model of the contact wire cross-section was constructed in Fluent

and the aerodynamic coefficients of the contact wire under different attack angles were obtained through the flow simulation. The static wind load model of the contact wire and the messenger wire was deduced by fluid induced vibration theory

based on a comprehensive consideration of the geometric nonlinearity of the catenary when the wind deflection occurs

the global stiffness matrix of the catenary was deduced using the absolute nodal coordinate method

and the three-dimensional nonlinear finite element model of the catenary was established. The wind deflection of the contact wire under the static wind load of different wind speeds and different initial wind attack angles was obtained by applying wind loads. Taking the actual catenary data as an example

the calculation results show that under different wind speeds and initial attack angles

the contact wire wind deflection generated by the static wind load on the catenary is affected by its aerodynamic coefficient

and increases with the wind speed. It is also very sensitive to the wind attack angle . When the wind speed is 30 m/s

the maximum lateral wind deflection of the catenary can reach 8.3% of the daily working length of the pantograph strip

which may lead to the occurrence of pantograph scraping accidents.
