摘　　要：基于结构仿生的原理,在分析典型分支结构的构型特点的基础上,设计了仿生型支架结构。有限元分析的结果表明,与原型结构相比,仿生型结构的质量减轻7.35%,最大应力和最大变形都明显减小。Based on structural bionic theory and after studying the configuration characteristics of typical branch structure,the structure of bionic support was designed.The finite element analysis（FEA） results show that,compared with the prototype structure,the weight of the bionic structure is reduced by 7.35%,maximum stress and deformation were also decreased significantly.
