| 摘 要： | 研究目的：研究高速列车车轮多边形特征对轮轨噪声和车内噪声的影响规律，讨论目前国内高速列车车轮镟修指标的不足，为高速列车车轮镟修方法的优化改进提供科学依据。创新要点：系统分析高速列车车轮多边形阶次、幅值和相位等参数对车内噪声的影响规律；提出车轮镟修中仅考虑车轮径跳作为限值是不够的。研究方法：1．基于线路试验，初步分析高速列车车轮多边形状态对车内噪声的影响，进而对车轮多边形特征进行剖析；2．基于带通滤波和快速傅里叶变换，使用MATLAB程序生成不同阶次、幅值和相位的车轮多边形粗糙度数据；3．基于TWINS轮轨噪声原理，使用HWTNS预测含有不同车轮多边形特性的轮轨噪声；4．基于混合有限元-统计能量分析（FE—SEA）方法，建立高速列车客室端部车内噪声预测模型，预测车内噪声；5．通过分析车轮多边形参数、车轮径跳和车内噪声之间的相互关系，研究目前的高速列车车轮镟修指标是否合适。重要结论：1．高速列车车轮径跳值相同，但车轮多边形状态不同时，轮轨噪声与车内噪声有明显差异；2．当车轮多边形幅值相同时，高阶多边形可以引起更高的轮轨噪声和车内噪声；3．改变车轮多边形的相位，可以获得不同的车轮径跳值，但是对轮轨噪声和车内噪声几乎没有影响。

| Abstract: | This work presents a detailed investigation conducted into the relationships between wheel polygonal wear and wheel/rail noise, and the interior noise of high-speed trains through extensive experiments and numerical simulations. The field experiments include roundness measurement and characteristics analysis of the high-speed wheels in service, and analysis on the effect of re-profiling on the interior noise of the high-speed coach. The experimental analysis shows that wheel polygonal wear has a great impact on wheel/rail noise and interior noise. In the numerical simulation, the model of high-speed wheel/rail noise caused by the uneven wheel wear is developed by means of the high-speed wheel-track noise soRware （HWTNS）. The calculation model of the interior noise of a high-speed coach is developed based on the hybrid of the finite element method and the statistic energy analysis （FE-SEA）. The numerical simulation analyses the effect of the polygonal wear characteristics, such as roughness level, polygon order （or wavelength）, and polygon phase, on wheel/rail noise and interior noise of a high-speed coach. The numerical results show that different polygon order with nearly the same roughness levels can cause different wheel/rail noises and interior noises. The polygon with a higher roughness level can cause a larger wheel/rail noise and a larger interior noise. The combination of different polygon phases can make a different wheel circle diameter difference due to wear, but its effect on the interior noise level is not great. This study can provide a basis for improving the criteria for high-speed wheel re-profiling of China＇s high-speed trains. |
