摘要
应用ABAQUS软件建立复合材料加筋板结构有限元模型,在轴向压缩载荷下,进行线性特征值屈曲分析。针对筋条参数、壁板参数及边界条件等影响因素,计算模型的临界屈曲载荷,对加筋板结构进行屈曲承载能力分析。结果表明:加筋条高度和条数、壁板铺层顺序和厚度及结构边界条件对屈曲载荷影响显著。
A finite element model of stiffened composite structure is established with ABAQUS.The buckling behavior is analyzed by the Linear Eigenvalue Method under axial compression.The critical buckling loads are computed using the modes.The buckling loading capabilities are affected by various factors,which include stiffener parameters,panel parameters and boundary conditions.Simulation result shows that the buckling loads are obviously affected by the height and numbers of stiffeners,the thickness and sequence of panel layers,and the boundary conditions.
