| description | ObjectiveIn order to meet the development trend of low weight and high strength in the design of compression shell structures for deep-sea submersibles, this paper proposes a structural enhancement method which involves winding a circumferential internal corrugated compression shell with a carbon fiber reinforced polymer (CFRP), then analyzes and optimizes the CFRP layering scheme. MethodFinite element simulation software ABAQUS is used to change the layering parameters of the CFRP according to the stress distribution of the composite layers, and the optimal winding angle under 14 layers of CFRP is explored to obtain the best layering scheme. The relevant strength failure criteria are then combined to check the intensity. ResultsThe results indicate that 40° is the best CFRP winding angle to enhance the circumferential internal corrugated compression shell. When the layering mode is (±40°2/±55°2/±70°2/90°2), the stress distribution between the layers is relatively uniform, meaning that the structure has a lighter weight while its strength fulfills the actual use requirements. ConclusionThe proposed structure can reduce the overall weight of deep-sea compression shells and push the development of the field toward lightweight design. |
