摘要
介绍了采用表面粘贴多孔材料的圆柱体试样,通过风洞试验,验证其降低空气动力噪声的效果,并在受电弓上粘贴金属多孔材料,也确认了可以降低空气动力噪声。
The cylinder sample which covers its surface with a certain porous material is described. The effect to reduce the aerodynamic noise is verified through the wind tunnel test. The porous metal material covered on the pantograph confirms that the aerodynamic noise can be reduced.
