Structural bionics for reinforcing frame of fuselage and wing joint

  • 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.
