When ostrich (Struthio camelus) runs, its tarsometatarsus swings at a high frequency and has a small mass but can carry the weight of the whole body, which is enough to indicate that tarsometatarsus has the lightweight and anti-bending properties. The results of scanning electron microscope (SEM) showed that there were no significant differences in the microstructure of different locations of tarsometatarsus. The compression test was performed, and the average compressive strength of the specimens at each sampling location was obtained. The results showed that the compressive strength of the tarsometatarsus in inside and outside orientations is smaller than that in front and back orientations. Therefore, the superior load-carrying capacity of tarsometatarsus is related to its morphological structure. Based on the morphological and structural characteristics of ostrich tarsometatarsus, the bionic tube was designed, and three kinds of tubes were designed as the control. Further, the finite element analysis of the anti-bending property of the four tubes was performed under static load. The result indicated that the bionic tube had lower mass and higher specific stiffness structural efficiency, and the result of the simulation was verified by the cantilever compression test.

基于鸵鸟的some骨的防弯曲轻质管中的仿生设计

当鸵鸟（鸵鸟双峰）运行时，它的酒石s以高频率摆动并且质量较小，但可以承载整个身体的重量，这足以表明酒石has具有轻巧和抗弯曲的特性。扫描电子显微镜（SEM）的结果表明，酒石tar不同部位的微观结构没有显着差异。进行压缩试验，获得在每个采样位置的样品的平均压缩强度。结果表明，骨在内侧和外侧的抗压强度均小于前后方向。因此，酒石tar的超强承载能力与其形态结构有关。根据驼鸟tar的形态和结构特点，设计了仿生管，并设计了三种管作为对照。此外，在静态载荷下对四个管的抗弯曲性能进行了有限元分析。结果表明，仿生管的质量较小，比刚度结构效率较高，通过悬臂压缩试验验证了仿真结果。
