| Abstract: | Stability analysis is the key of designing the pressure-proof spherical shell of the manned submarine. Based on the secondary development of CATIA, the communication between the CATIA parametric model and the finite element analysis software ABAQUS is achieved, the automatic meshing of variable parameter model is realized by using the Python programming language of ABAQUS, and the inertial boundary is set by Inertia Relief. On the foundation of studying the stability solution method based on the arc length method, the effectiveness of the stability calculation method is verified with the MT-1 model. Finally, the parametric design and stability calculation method are applied in practical design, resulting in enhancement of the efficiency of designing pressure-proof spherical shells. |
