航空航天结构中的复合材料层合板开口补强问题一直受到关注。以含中心矩形开口复合材料层合板为研究对象，在拉伸、压缩、剪切载荷下采用不同补强材料及不同补强形式，使用modeFrontier软件与ABAQUS软件集成优化的方式，对补强结构参数进行了优化设计。对不同补强形式、不同补强材料下最优化结构质量进行对比分析。研究表明，三种补强方式中插层补强最优化结构形式最优，补强后结构质量最轻。%Reinforcing structure for composite laminates with cutout is paid atlention to. Composite laminates with center rectan-gle opening are investigated. The integrated optimization method of modeFrontier and ABAQUS is used on certain laminates under different load cases: tension, compress and shear. The parameters of different reinforcement types with different materi-als are optimized to satisfy the objective weight function. The weight characteristics of the reinforced structure are also com-pared and analyzed. The research indicates that compared with other two reinforcement types, intercalation reinforced structure is the lightest.
