摘要
通过建立轮轨噪声预测模型,给出了车轮、钢轨辐射噪声声压级谱计算式。利用有关文献中的数据,对轮轨噪声进行了预测。从轮轨接触表面的不平顺、车轮、钢轨和声源等角度讨论了轮轨噪声的控制。
By establishing a wheel/rail noise prediction model, the paper calculates the total sound pressure level spectrum caused by the wheel/rail interaction, predicts the wheel/rail noise based on the data from the associated literature. The authors argue that the wheel/rail noise shall be reduced through the control of the irregularity on the contact surfaces between the wheel and the rail, the noise transmission of the wheel and the rail, and the sources of other noises.
