水下结构辐射噪声工程估算方法研究

Engineering Estimation of Noises From Submerged Structures

在总结国内外关于结构噪声预报和估算方法的基础上 ,提出了一种基于统计假设下的估算方法 .该方法以理论分析和实验研究为基础 ,在确定了结构噪声的辐射效率后 ,再通过直接或间接法获得结构表面均方加速度分布 ,即可实现水下结构辐射噪声的工程估算方法 .另外 ,还进行了对比实验研究 ,实验研究结果表明 ,该估算方法简单可行 ,便于在实际工程中的应用 ;但对其适用性 。

Based on experiences gained from prediction and estimation of noises from submerged structures both at home and abroad,a new engineering estimation method is proposed for estimation of noises from submerged structures,which combines theoretical analysis with experimental research on the distribution of average square acceleration on the structure surface to achieve simplicity and high_precision.
