摘　　要：针对部分高速动车组车辆在服役初期出现的异常振动噪声问题,从车内噪声特性与车轮非圆化间的量化关系为着眼点,通过车轮多边形阶数与振动噪声频率之间的分析,探究了二者间的对应关系,为高速动车组车内噪声的抑制提供了技术支持.Aiming at vibration noise problems of some high-speed EMU trains in service process, the effect of non-round and smooth wheel characteristics on interior noise is studied based on the relation between interior noise characteristics and non-round and smooth wheel by quantitative relationship. The result can provide tech- nical support for high-speed EMU interior noise suppression.
