Due to the good pressure capacity and designability, the stiffener design and buckling analysis of stiffened spherical shell have always been classic and challenging problems. In this paper, the parametric finite element modeling method of stiffened spherical shell based on ABAQUS is given, and the parametric finite element model of the stiffened spherical shell is established, which greatly improves the efficiency of the finite element modeling.. The accuracy of the model is verified by comparing with literature data. Using the critical buckling pressure Pc and the critical buckling pressure to weight ratio Pc/W as main indexes, the influence of shell thickness, stiffener layout, stiffener section size and other parameters on the buckling of aluminum alloy stiffened spherical shell is studied. The finite element analysis results show that circumferential stiffener has more significant influence on the overall buckling of the structure, while the influence of meridional stiffener is not obvious. Increasing the shell thickness and the section height of the reinforcement can also effectively improve the buckling performance of the stiffened spherical shell.
