A Wave Superposition–Finite Element Method for Calculating the Radiated Noise Generated by Volumetric Targets in Shallow Water

China Ocean Engineering 2024年第5期38卷 845-854页

作者： TANG Yu-hang ZHAO Zhe LI Hai-chao PANG Fu-zhen TANG Yang DU yuan Naval Research Institute College of Shipbuilding Engineering Harbin Engineering University School of marine Engineering and Technology Sun Yat-sen University

A combined method of wave superposition and finite element is proposed to solve the radiation noise of targets in shallow sea. Taking the sound propagation of spherical sound source in shallow sea as an example, the radiation sound field of the spherical sound source is equivalent to the linear superposition of the radiation sound field of several internal point sound sources, and then the radiated noise induced by spherical sound source can be predicted *** accuracy and efficiency of the method are verified by comparing with the numerical results of finite element method, and the rapid prediction of underwater radiated noise of cylindrical shell is carried out based on the *** results show that compared with the finite element method, the relative error of the calculation results under different simulation conditions does not exceed 0.1%, and the calculation time is about 1/10 of the finite element method, so this method can be used to solve the radiated noise of shallow underwater targets.
