Abstract: This paper focuses on the pressure resistance of underwater equipment. A shell structure that divided into multi-layer is proposed, the spaces between layers are filled with fluid medium, which is applied gradually decreasing pressure in outside-inside order that helps offsetting external pressure. Using the Finite Element Method, the Multi-layer Fluid-Solid-Coupling Shell Structure has been proved to be effective in improving the pressure resistance of underwater equipment without increasing the total thickness of material, in the scope of the study, the maximum equivalent stress of the whole structure decreased with increase of the number of layers without instability phenomenon.
