| description | The layout merits of wing internals can influence the weight of wing structure greatly, so it is necessary to perform the layout optimization design. The concurrent subspace optimization method is used to solve the layout optimization problem of wings, by which the layout optimization problem is divided into three subspaces of spar location, stringer and thickness optimization, and the design variables are optimized in their own subspace separately. After the optimization of each subspace. The design variables are coordinated in the system to maintain the optimization variables of the subspace with lightest weight unchanged. The approximate one-dimensional search method is used to coordinate the design variables of other subspace, and the variables are iterated until convergence. The results show that the method has high optimization efficiency, can obtain better optimization results, and has practical engineering value. |
