摘要
文章通过研究分析不同结构和安装位置的导流板对调节高速受电弓与接触网间动态接触力的影响,探讨高速受电弓在不同运行条件下导流板的选型策略。在基于风洞试验和实车线路试验结果上,对实际运用较广的弧形导流板进行Fluent仿真研究,分析其在受电弓开口、闭口运行条件下不同的气动力作用机理,总结弧形导流板在受电弓高速运行条件下气动力关于安装倾角的特性曲线,为导流板优化安装调节方案,提供理论指导与运用参考。
This paper studied how the airfoils with different shapes and different installation position influenced the dynamic contact force between the high speed pantograph and catenary.The study shows different selection strategies of airfoil according to different working condition.Based on the results of wind tunnel experiment and running test,the widely used arc-shaped airfoil was chosen to be the object of simulation.The simulation results show the different mechanisms of aerodynamic force while pantograph was on different working conditions.The aerodynamic force-attack angle characteristic curve is obtained to be the reference for adjustment.
