摘　　要：基于全机有限元模型建立了下壁板维修孔细节有限元模型。在细节有限元模型基础上定义了自由尺寸优化设计模型。以机翼整体柔度最小为目标进行自由尺寸优化设计。优化结果表明,为最小化翼盒整体柔度,下壁板维修孔两侧需要多分布材料以加强设计,而维修孔之间需要少分布材料以减弱设计。Based on the detail finite element model of access hole region on the lower panel, a free size optimization model has been developed.The task of free size optimization is done with the minimum flexibility of the wingbox as the objective. The results show that more material should be located besides the access holes and less material between the access holes in order to minimise the flexibility of the wingbox.
