随着高速列车运行速度的不断提升，空气动力使得弓网的垂向振动、纵向冲击、横向摆动和弓网耦合振动越发明显，弓网的离线更加频繁，受流质量严重恶化。本文在总结归纳国内外已有研究成果的基础上，阐述了数值仿真计算、风洞试验和线路试验的弓网空气动力学研究方法；分析了受电弓的气动特性和减阻降噪措施以及接触网风场模拟、风振响应、接触线气动特性研究的最新进展。针对现有弓网空气动力学研究的不足，指出弓网空气动力学研究目前存在的问题，展望了弓网空气动力学未来发展趋势。

With the increasing speed of high-speed trains,aerodynamic force,which results in increasing vertical vibration,longitudinal shock,horizontal swing and pantograph-catenary coupling vibration,causes frequent de-tachment between pantograph and catenary,seriously affecting the quality of current collection.Based on do-mestic and international research findings,this paper presents the research methods,including numerical simu-lation,wind tunnel tests and line tests,on pantograph-catenary aerodynamics.Aerodynamic characteristics of pantograph and air noise and resistance reduction methods are analyzed.The latest progress on the research of wind field simulation,catenary wind vibration responses and contact wire aerodynamic characteristics is intro-duced.With regard to the lack of sufficient research on pantograph-catenary aerodynamics,this paper points out existing problems in the study of pantograph-catenary aerodynamics and presents the research trend there-of.
