ON BIOMIMETICS IN MACHINE ELEMENTS DESIGN
Presentation of the lecture prepared for conference ICAMEN2019
The idea of imitating Nature has been developed 3000 years ago, when the Chinese attempted to make artificial silk and roughly at the same time another imitation of Nature that most likely resulted from humans observing the spider using its web to catch flies occurred – fishing nets. But, it can be said that man has always drawn on Nature for inspiration. Leonardo Da Vinci designed ships based on the shapes of fish and planes based on the wings of birds.
The discussion and the results of the application of biomimetics principles in machine elements design are given. The basic definitions and history of the developing of this discipline are presented. The biomimetics is one of the inter-disciplinary disciplines which reach their full attention during last decade. The engineers are realizing the benefits which can be gained by the biomimetics principles according with the new requirements in machine design such as: size reduction, energy efficiency increasing and higher reliability. Therefore, biomimetics has intents to grow up in a new and progressive discipline widely use in machine elements design.
In this lecture, the focus is on the geometric optimizations in machine elements design based on the nature design as inspiration. As the example of the machine elements design based on the biomimetics principles, the new design for the transition zone of the particular high loaded shaft is developed and analyzed. The new design is inspired with the design solutions which Nature made in the case of trees. The comparative Finite Element Analysis is performed for both transition zone designs: the traditional engineering design and the design based on the biomimetics. The conclusions about the increased load capacity obtained with innovative biomimetics design are discussed.
Seminar Mehanika mašina i mehanizama - modeli i matematičke metode započeo je sa radom u junu 2018.god. Seminar se održava do dva puta mesečno, utorkom u periodu od 17.00 - 19.00 u Matematičkom institutu SANU.
