To promote the development of light weight aeronautical structure under the booming new manufacturing technology, three promising layouts of sub-stiffened thin wall structures are proposed and the corresponding design optimization regarding the structure's buckling behavior are conducted based on numerical simulation. A design optimization framework of sub-stiffened structure is developed based on the multidisciplinary optimization platform ModelCenter and finite element method (FEM) software ABAQUS. The framework is applied for the optimal designs of the three panel layouts with particle swarm optimization (PSO) algorithm. Three optimal sub-stiffened panels are acquired while the performance gains of critical buckling load and ultimate strength under uniaxial loading after sub-stiffening is introduced to the benchmark panel structure are analyzed. The result indicates that the introduction of sub-stiffening to the traditional stiffened panel can significantly improve the panel's buckling load and ultimate strength under uniaxial loading, and thus deserves further attention for aerospace industry which endeavors to develop high performance light weight structures with new manufacture technology.
