中文摘要:
      栅格加筋板的主要失效形式为整体屈曲和局部屈曲,据此提出了一种栅格加筋板布局的并行协同优化方法,该方法将设计变量分为整体设计变量与局部设计变量,在两个子空间中并行优化,然后进行系统级协调,反复迭代至收敛。本文完成了两个典型算例,算例结果表明:本文所提方法优化流程清晰、算法稳定、结果可靠,可以获得最优解。
英文摘要:
      Based on the fact that the main failure modes of stiffened panel are global buckling and local buckling, a concurrent optimization method for the layout of stiffened panel is proposed. The design variables are divided into global design variables and local design variables. The two groups of variables are optimized concurrently in two subspaces, and then coordinated at the system level until convergence by means of repeated iteration. Two typical examples are completed in this paper. The results show that the proposed method has clear optimization process, stable algorithm and reliable outcomes, and can obtain the optimal solution.
