对运营中的高速列车进行车内振动与噪声现场测试，分析高速列车车内振动和噪声特性，明确车内振动与噪声的水平及频谱特性，同时对车轮表面粗糙度进行同步测试，分析车轮非圆化特征，研究车轮径跳幅值及车轮多边形阶次对高速列车车内振动与噪声的影响。结果表明，车轮第20阶多边形是使车内振动和噪声偏大，并形成580 Hz显著频率的主要原因，相关结果可为高速列车车内振动与噪声控制及指导车轮镟修提供参考。
對運營中的高速列車進行車內振動與譟聲現場測試，分析高速列車車內振動和譟聲特性，明確車內振動與譟聲的水平及頻譜特性，同時對車輪錶麵粗糙度進行同步測試，分析車輪非圓化特徵，研究車輪徑跳幅值及車輪多邊形階次對高速列車車內振動與譟聲的影響。結果錶明，車輪第20階多邊形是使車內振動和譟聲偏大，併形成580 Hz顯著頻率的主要原因，相關結果可為高速列車車內振動與譟聲控製及指導車輪鏇脩提供參攷。

The interior vibration and noise of a high-speed train are measured. Their characteristics are analyzed and the sound pressure/vibration level and the spectra are obtained. Meanwhile, the out-of-roundness of the wheel is also measured simultaneously to study its influence on the interior vibration and noise. The effects of the high-order polygonal wear and radial run-out of the wheel are analyzed. It is found that the 20 th order polygonal wear of the wheel, corresponding to the passing frequency of about 580 Hz, plays a significant role in the high interior vibration and noise. The data shown in this work provides a significant contribution for design of the low-noise trains and improvement of wheel’s re-profile techniques.
