Simulation of Compress Buckling Performance of Composite Stiffened Panel

摘要：

　　Finite element method is applied to analyze the buckling performance of composite stiffened panel.Compress buckling critical loads of six types panels with T or Z-section stiffeners are calculated by FEM.The emulational calculation results show that with same cross section area,critical buckling load of panel with T-section stiffeners increases with the reduction of stiffener pitch and the increase of stiffener numbers,while the buckling load of panel with Z-section stiffeners increases to a certain level and then keep almost changeless.To T-section stiffener panels,the relation between thickness of skin and buckling load is approximately quadratic trinominal.Conclusions obtained can offer a referenced measure for the optimization design and engineering application of the structure.
