| 摘 要： | 讨论了湍流边界层激励下声呐腔自噪声统计能量分析。采用圆柱一圆板组合结构模拟艏部声呐罩，重点讨论了湍流边界层输入功率计算，及利用均值导纳法求解多耦合结构之间的直接耦合损耗因子及问接耦合损耗因子，给出了详细的理论推导，最后给出了具体的算例。分析结果可作为湍流边界层激励下声呐腔自噪声工程估算的参考。

| Abstract: | A computing model for the self-noise due to sonar cavity is established by using SEA method. The model is a combination of a circular cylinder and circular plate to resemble the sonar dome. The emphases are put on the calculation of input power form the turbulent boundary layer to the sonar dome and SEA parameters. A detailed example is given to validate the model. Therefore, this paper can be useful for further discussions on such problems. |
