| 摘 要： | 由于工艺性、维护性等要求，复合材料结构梁腹板中不可避免需开孔，不同形式的开孔有着不同承载能力。通过对梁腹板结构不同形式的开孔进行剪切载荷下屈曲试验研究，得到屈曲载荷和破坏载荷，对比不同开孔对结构承载的影响，并通过有限元进行数值模拟分析，屈曲载荷和试验基本吻合。同时试验得到复合材料结构有较强的后屈曲承载能力。

| Abstract: | In order to satisfy the technics and maintenance requirements for the structure of the composite web,holes are ineluctable on the web of spar and difform holes have different carrying capacity. By studying difform holes on the web with buckling test under the shear load , different buckling load and failure mode of structure are established. Finite element analysis was used to analyze the buckling behavior of the web, and the analysis results are accordable with experimental results. Experiment results also reveal that the composite web can bear greater load after buckling. |
