为设计并开发轻量型仿生复合材料,分析了东方龙虱鞘翅断面的微观结构,发现龙虱鞘翅的内部空腔结构为非贯通球形空腔。受龙虱鞘翅独特结构的启发设计了一种轻质仿生结构,球形空腔以正六边形的形式分布于该结构内部。为考察该仿生结构的力学特性,引入了两种常见的中空结构,并借助有限元分析软件ANSYS分别对该仿生结构和其他两种常见的中空结构的压缩、拉伸及弯曲性能进行了有限元分析和对比研究。结果表明:该仿生结构较其他两种常见的中空结构具有更强的抗压能力、抗拉能力及更高的屈服强度,力学性能优异。该仿生结构在材料结构方面为研制新型仿生复合材料提供了仿生学参考。
In order to design and develop a lightweight biomimetic composite material, the microstructure of the oriental louse sheath was studied. The internal cavity structure of the sheath sheath was found to be non-through spherical cavity. Inspired by the unique structure of the dragonfly’s coleoptile, a lightweight biomimetic structure has been designed. The spherical cavity is distributed in a regular hexagon inside the structure. In order to investigate the mechanical properties of the bionic structure, two kinds of common hollow structures were introduced. The finite element analysis software ANSYS was used to analyze the compression, tensile and bending properties of the bionic structure and two other common hollow structures respectively. Analysis and comparative study. The results show that the bionic structure has better compressive strength, tensile strength and higher yield strength than the other two common hollow structures, and has excellent mechanical properties. The bionic structure provides a bionic reference for the development of new bionic composite materials in terms of material structure.
