| 摘 要： | 相似是仿生的基础,全面系统地理解工程原型的功能需求和生物体各个层次的优异结构,准确把握生物体与工程原型的相似性,是结构仿生设计的关键.为减轻翼身结合框重量,分析了竹干与翼身结合框相似的承力性能,借鉴竹干的细观结构形状和排列方式,应用结构仿生原理设计了仿生翼身结合框.有限元分析结果表明,在保证结合框强度、刚度的前提下,仿生结构与原型相比重量可减轻2.1％.

| Abstract: | Similarity is the base of bionics. Comprehensive explanation of functional demand in engineering prototype and superiority of biologic structures in all levels, accurate understanding the similarity of organisms and engineering prototype, these are the key of the bionic structure design. To decrease the weight of an aircraft reinforcing frame, the similarity in loading feature with bamboo and an aircraft reinforcing frame was analyzed. Based on the bamboo’s meso-structure shape and its arrange way a reinforcing frame was designed by applying the biomimetics principle. The FEA results show that the weight of the bionics frame decreased by 2.1% in ensured strength and structural stiffness compared with the original design. |
