摘　　要：地铁车辆异响振动源不同而发生不同程度异响。本文以华东地区某地铁线为例,从轮轨噪声、气流噪声和牵引动力噪声来分析地铁轨行区产生异响的原因。以期为本行业判断和排除正线异响提供参考。Subway vehicles have different vibration sources and have different degrees of abnormal sound.Taking a subway line in East China as an example,it occurs from wheel-rail noise,air flow noise and traction power noise.In order to provide a reference for the industry to judge and exclude the abnormal ring of the positive line.

关 键 词：地铁 异响 轮轨噪声 气流噪声 牵引动力噪声
