A lightweight design method was put forward with the combination of bionics and structure optimization design. On the basis of similarity analysis, the bionic design of structure is carried out. By employing the central composite design (CCD), the sample points of finite element analysis (FEA) are selected to construct the second-order polynomial response surface model (RSM). Without increasing the...
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...
