Geometric optimization of transition zones based on biomimetics principles

Abstract

The basic definitions and a history of the development of biomimetics as a discipline thatconsiders nature-inspired design are presented in this paper. The discussion and the results of theapplication of principles of nature-inspired design in machine elements design are given. The factthat transition zones that Nature chose and designed on trees in many cases survived for morethan a hundred years, resisting on the various and variable external loads and other externalconditions, is considered. Presented case study used the nature-inspired transition shapes in theresearch of innovative design and geometric optimization of transition zones of high-loadedshafts. The comparative Finite Element Analysis is performed for a particular transition zone withtraditional engineering design, as well as with nature-inspired design. The conclusions about theincrease of load capacity that is obtained with innovative biomimetics design are discussed.
