摘　　要：薄壁结构的屈曲行为可能在平面内荷载的作用下发生,从而导致整个结构的不稳定和承载能力的下降。因此,有必要进行代表结构稳定性的屈曲强度的分析研究。本文重点研究了低碳钢和铝合金制成的金属板,以及不同堆叠顺序的AS/3501-6石墨/环氧树脂纤维增强层压复合材料板,采用有限元方法(Abaqus)建立了其不同边界条件下的平板模型和四边简支条件下的加筋板模型。研究结果表明,不同的材料特性、边界条件、堆叠顺序以及加强筋数量和高度都会影响薄壁板的屈曲荷载能力。The buckling behavior of thin-walled structures may occur under the action of in-plane loads,which leads to the instability of the whole structure and the decline of the bearing capacity.Therefore,it is necessary to analyze the buckling strength which represents the stability of the structure.This paper focuses on the study of metal plates made of low carbon steel and aluminum alloy,and AS/3501-6 graphite/epoxy fiber reinforced laminate composite plates with different stacking sequences.The finite element method(Abaqus)is used to establish the plate model under different boundary conditions and the stiffened plate model under four side simply supported conditions.The results show that different material properties,boundary conditions,stacking sequence and the number and height of stiffeners will affect the buckling capacity of thin-walled panels.
