    摘要:

    高速航行时的水下航行器的水动力噪声问题一直尤为突出，水动力噪声分为流体脉动压力直接辐射声与流激噪声，流激噪声是结构表面受到湍流脉动压力引起结构振动产生的噪声。由于湍流扰动的随机性，表面脉动压力时空不均，在计算流激噪声时需要统计分析方法的介入。湍流边界层脉动压力的计算方法主要包括传统的半经验公式法计算和 CFD 流场分析计算，将二者相结合对流激噪声进行预报，在流场仿真中提取出频率波数谱预测模型所需的参数，分别使用有限元法和统计能量法代入并计算，对比结果与理论经验公式方法得到的结果，二者的噪声结果较为吻合。

    Abstract:

    The hydrodynamic noise of underwater vehicles during high-speed navigation has always been particularly prominent. Hydrodynamic noise is divided into direct radiation noise of fluid pulsating pressure and flow-induced noise. Flow-induced noise is generated by structural vibration caused by turbulent pulsating pressure on the structural surface. Due to the randomness of turbulent disturbances，the surface pulsating pressure is not uniform in time and space，so the statistical analysis method is needed to calculate flow-induced noise. The calculation methods for turbulent boundary layer pulsating pressure mainly include traditional semi-empirical formula calculation and CFD flow field analysis calculation. Flow-induced noise calculation uses method combined with these two，extracting the parameters required for the frequency wavenumber spectrum prediction model in flow field simulation，and respectively using the finite element method and statistical energy method for calculation. The results are compared with those obtained from theoretical empirical formula methods，and the noise results of the two are quite consistent.
