摘要
以国内受电弓制造商研制的新型高速受电弓为研究对象,通过风洞试验对新型高速受电弓的空气动力学性能从气动抬升力和气动总阻力两个方面进行研究,同时结合两种试验数据对该新型高速受电弓的气动抬升力性能进行分析,通过数据拟合得出气动抬升力与风速的关系式,最后通过线路运行试验进行了验证。
This essay mainly research the aerodynamic performance of a new type high-speed pantograph which is made by the domestic pantograph manufacturer.The aerodynamic performance of the new high-speed pantograph is studied from the two aspects of aerodynamic lifting force and total aerodynamic drag by wind tunnel test.The test data is used to analyze the aerodynamic lift performance of the new high-speed pantograph.The relationship between the aerodynamic lift force and the wind speed is obtained by data fitting.Finally,it is verified by the line running test.
