| Abstract: | Mainly solves the problem about choice lage. In this paper, the finite element model of the of stiffened structure configuration of laminated composite fusestructure was modeled in Patran and analyzed preliminarily by Nastran to get the element force. Then the finite element model is imported into Hypersizer to calculate and optimize, then the optimal stiffened structure type of laminated composite fuselage is attained. The research of model- ing, analysis and optimization has practicable engineering value. |
