The invention discloses a bionic unmanned aerial vehicle body bearing structure which is characterized by sequentially comprising multiple stages of reinforcing ribs from the center to the periphery.The number of the stages of reinforcing ribs from the center to the periphery is gradually increased; the multiple reinforcing ribs of the outer stage are connected to one reinforcing rib of the innerstage, and the multiple reinforcing ribs of the same stage are diverged and separated from one another in the same plane. The structure is based on a bionics principle; a novel bionic unmanned aerialvehicle body bearing structure is designed on the basis of the structural characteristics of the veins of the prinsepia utilis; because the reinforcing ribs imitating the veins of the prinsepia utilis have special distribution and arrangement, when the structure makes contact with airflow, under the action of impact loads, the transmission mode and position of the impact loads are changed under the action of the reinforcing ribs, stress concentration is effectively relieved, energy generated in the impact process is reasonably distributed, and the impact resistance of the structure is improved.

    本发明公开一种仿生无人机机身承载结构,其特征在于,由中心到外围依次包括多级加强筋,并且中心到外围每一级加强筋的数量逐渐增加;外一级的多个加强筋连接在内一级的一个加强筋上,同一级的多个加强筋在同一平面内相互发散分开。本发明是根据仿生学原理,并基于王莲叶脉结构特征设计成一种新型的仿生无人机机身承载结构,由于仿王莲叶脉的加强筋具有特殊的分布和排列,当结构与气流相互接触时,受到冲击载荷的作用,在加强筋的作用下,冲击载荷的传递方式和位置发生改变,有效的缓解了应力集中,合理分布了冲击过程中产生的能量,提高了结构的抗冲击性能。
