From the perspective of biomechanics, this paper studies the outer surface of the rachis. The bio-structure was determined by microscopy. Finite element analysis was conducted on this bio-structure. The results show that, in the feather, the bio-structure of the outer surface of the rachis consists of the basic unit structure of the hexagonal shape of the edge protrusion and a small number of pentagons. The results of the finite element analysis for the basic geometry structure and flange were the edges of which the main bearing stress sites. The practical reference value was for the determination one of safety-structures.
