Stiffened plates are widely used in aerospace structures as load-bearing components. In order to obtain a novel design of stiffened structures with excellent performance, a generative design method of stiffened plates (GDMSP) based on the homogenization method is proposed in this paper, which optimizes the stiffener layout based on an equivalent model. Then, the detailed model can then be obtained by extracting the stiffener path from the discrete distribution of stiffener angles. Moreover, the optimized design can be obtained by size optimization based on the detailed model. Two examples are used to illustrate the proposed framework, including the stiffness maximization of a rectangle stiffener plate and the buckling load maximization of a square stiffener plate. The optimized stiffener configurations are characterized by streamlines and uniform lines, respectively. For the first example, the stiffness of the stiffener design has an improvement of 17%. For the second example, the optimized design improves the buckling load by 35%. Results indicate that the proposed method can effectively provide a novel generative design for stiffened plates. Moreover, the obtained results have a clear stiffener path and have a noticeable improvement in performance, which can be directly used to establish a detailed model.

加筋板作为承重部件广泛应用于航空航天结构中。为了获得性能优异的加筋结构新颖设计，本文提出了一种基于均质化方法的加筋板生成设计方法（GDMSP），该方法基于等效模型对加筋板布局进行优化。然后，可以通过从加劲肋角度的离散分布中提取加劲肋路径来获得详细模型。此外，优化设计可以通过基于详细模型的尺寸优化来获得。两个例子用于说明所提出的框架，包括矩形加强板的刚度最大化和方形加强板的屈曲载荷最大化。优化的加强筋配置分别以流线和均匀线为特征。对于第一个示例，加劲肋设计的刚度提高了 17%。对于第二个示例，优化设计将屈曲载荷提高了 35%。结果表明，所提出的方法可以有效地为加筋板提供一种新颖的衍生式设计。而且，所得结果具有清晰的加劲肋路径，并且在性能上有显着改善，可直接用于建立详细模型。
