Design of the transition zone of turbine shaft to flange by biomimetics principles

Abstract

The consideration of the optimal design of the transition zone of turbine shaft to flange has a high impact within the turbines design. The main principles of biomimetics give a new and prosperous point of view on the machine design, and could recommend a new options in the design solutions for the zones with high stress concentrations. In this paper, a particular turbine shaft with flange is used for research of the possible biomimetics solutions in the zone of the transition radius. The traditional design of this transition zone is compare with the new design option inspired with transition zones in nature. The presented turbine shaft to flange design by biomimetics principles are based on the design of transition zones on trees. The Finite Element Analysis is performed for the traditional designed transition zone, as well as for the transition zone with design based on the biomimetics. The comparative analysis of the obtained results lead to the conclusions about the advantages of the biomimetics approach in this area of machine design.
