    摘要:

    综述桥梁结构噪声的产生机理、桥梁结构噪声的频谱特性、结构噪声与列车速度的关系以及桥梁结构声辐射效率的影响因素。简要介绍结构噪声的分析计算方法及其进展并讨论了每种方法的不足。从减隔振、限制振动传播和能量衰减方面总结了控制结构噪声的措施,提出减小桥梁结构噪声中有待研究的问题。

    Abstract:

    The generating mechanism of bridge structure-borne noise, the spectral characteristics of structure noise and the relation between structure noise and train speed and the influence factors of bridge radiation efficiency are introduced. In the paper, plural calculation methods and the present progress are briefly introduced.The defects of each method are pointed out. Strategies for reducing the bridge structure noise are include vibration reduction/isolation, vibration transmission/limitation and energy attenuation. The problems of reducing the structure-borne noise are pointed out for further studies.
