摘　　要：通过建立“非离散模型”对复合材料加筋圆柱曲板进行了总体失稳分析研究，重点研究了边界条件影响和简化方法，推导了加筋圆柱曲板整体失稳的筋条“抹平”计算方法，并通过算例与试验结果进行了比较。结果表明该算法对筋条两对边为简支或固支时的总体失稳分析具有较高精确度，同时对实验的加载方法有一定指导意义。By model with no discretization, general buckling of composite stiffened cylindrical panel is designed. It is focused on the influence of boundary condition and the simplified method of boundary condition. General buckling load is computed by use of ＂smeared out＂ stringers as an equivalence panel. The analysis results using this model have been compared with experiment results. It demonstrates that this method is accurate in the general buckling analysis and available for test of composite stiffened panel.
