摘要

提出了一种轻量化仿生设计方法对结构进行加固。为了优化加筋板的形状和分布，研究了叶脉和蜂窝的特性。基于生物结构特性，对基础结构加劲板进行了结构仿生设计。然后，通过有限元分析对初始结构和仿生结构的静态性能进行了比较，验证了所提方法的有效性。结果表明，仿生型的质量分别减少了12.46%和8.02%，最大变形量分别减少了5.45%和3.58%。从而验证了该方法的有效性和适用性。

Structural bionic lightweight design for the stiffened plate of base structure

A lightweight bionic design method is proposed to reinforce the structure. The characteristics of leaf vein and honeycomb are investigated to optimize the shape and distribution of the stiffened plate. The structural bionic design for the stiffened plate of base structure is carried out based on biological structure characteristics. Then, a comparison of static performance between initial and bionic structures is conducted to verify the proposed approach by employing finite element analysis. The results show that the mass of the bionic types is reduced by 12.46% and 8.02%, the maximum deformation is reduced by 5.45% and 3.58%, respectively. And thus the validity and applicability of this method is verified.
