| Abstract: | The ultimate strength of the manned submersible is the guarantee of safety which is a key factor in design and manufacture procedure. In this paper, the ultimate strength analysis of manned deep-sea submersible is carried out on the base of nonlinear finite element method. Based on the results, the factors which influence the ultimate strength of manned deep-sea submersible are brought out. Furthermore, the comparision of ultimate strength of manned deep-sea submersible between nonlinear finite element method and new design formulae is carried out indicating that the nonlinear finite element method and new design formulae have wide applicability, which lays a foundation for the enaction of rules and guidelines for construction and inspection of manned deep-sea submersible. |
