高速列车受电弓风洞试验研究

为了研究高速列车受电弓在较高速度下的整体气动特性、弓网接触压力以及受电弓对支持绝缘子的作用力等综合性能，在FD-09低速风洞中进行了测力试验。试验采用测力天平和力传感器进行测量。通过在FD-09风洞试验段内安装收缩地板的方式首次将受电弓试验风速提高到了380km/h，可以满足高速列车受电弓高速性能研究的需求。研究结果表明：受电弓相对列车运行方向对受电弓升力特性有显著的影响，对弓网接触压力也有较大的影响；通过调节导风板的角度可以有效控制弓网接触压力；受电弓对支持绝缘子的作用力表现为前面拉力后面压力。

Experimental Study of High-Speed Train Pantograph in Wind Tunnel

In order to study the overall aerodynamic characteristics of high-speed train pantograph, the pantograph-catenary contact pressure and the force between pantograph and supporting insulator, when train is traveling at higher speed, force measurement was conducted in a FD-09 low-speed wind tunnel. Force balance and force sensors were used in test. By installing retractable floor in FD-09 wind tunnel test section, the maximum speed of wind acting on pantograph reached 380km/h for the first time, which can meet the high-speed test demand of pantograph. Results indicate that the relative direction of pantograph to train travelling direction presents remarkable effect on pantograph lift characteristics and the pantograph-catenary contact pressure; the pantograph-catenary contact pressure can be effectively controlled by adjusting the angles of air deflector; the forces between pantograph and supporting insulator are pulling forces in front position and pressure force in back position, respectively.
