Abstract
Due to the need for an ocean voyage, the shape and material of pressure-resistant structures of submersibles need to meet higher requirements. At present, the static mechanical properties of pressure-resistant systems have been extensively studied. However, it is still necessary to further explore its acoustic radiation noise to provide a reference for the overall acoustic design. A combination of the finite element method and wave superposition method (FEM-WSM) is used to calculate the acoustic radiation field of axisymmetric pressure-resistant structures in the ocean environment. Taking spherical, egg-shaped, and multi-body egg-shaped shells as examples, explores the distribution of acoustic radiation field of axisymmetric pressure-resistant shells under different shapes, materials, and submerging depths.
