| 摘 要： | 在对自然界分枝系统形态的最优性及其成长机理的研究基础上,以薄板结构的加强筋分布设计为例,提出了一种自适应成长设计法。在给定的载荷及支撑条件下,薄板结构的加强筋从事先选定的一些“种子”出发,在有限元分析的基础上,遵循自适应成长规律,沿着能使结构整体刚度最大的方向成长。对一些典型的薄板结构进行了设计,设计结果表明所提出的方法比现有的设计方法简单而高效。 |
| 关 键 词： | 加强筋分布 自适应成长 拓扑优化设计 仿生设计 最大刚度 |

| Abstract: | The paper applied the growth mechanism of branch systems in nature to topology design optimization of engineering structure. It suggested an innovative design method termed adaptive growth technique by studying the optimality and growth mechanism of branch systems in nature. In the case of rib distribution design problem of thin plate structure, the ribs graw from so-called seeds specified in advance and graw adaptively towards such directions that cowd make the global stiffness of the structure greatest. Rib distributions of some typical design problems were illustrated. The design results show the suggested method is simple and effective. |
| Keywords: | rib distribution adaptive growth topology design optimization bionic design maximum stiffness |
