采用CFD分析法,对弓头及其支架连接区域的涡流结构和噪声源结构进行了分析,指出改进型支架与最佳型弓头组合对降低受电弓的空气动力噪声非常有效。
The CFD analysis method was used to analyze the structure of vortex and the structure of noise source in the connecting area of bow and its support. It was pointed out that the combination of improved support and optimal bow was effective in reducing the aerodynamic noise of pantograph.
