This paper presents the analysis of a linear stiffness model of an elliptical flexure hinge. The purpose of the study is to support the mechanical designer in choosing the geometric dimensions of the hinge based on design specifications, driven by the accuracy that can later be achieved in planning its motion using the related stiffness model. Results are presented as a comparison between the analytical model and a finite element model of the flexure hinge, showing the practical range of applicability of the analytical model and its limitations. A case study show how to design a flexure hinge of small size for micro scale robotic or mechatronic operations.

Abstract
This paper presents the analysis of a linear stiffness model of an elliptical flexure hinge. The purpose of the study is to support the mechanical designer in choosing the geometric dimensions of the hinge based on design specifications, driven by the accuracy that can later be achieved in planning its motion using the related stiffness model. Results are presented as a comparison between the analytical model and a finite element model of the flexure hinge, showing the practical range of applicability of the analytical model and its limitations. A case study show how to design a flexure hinge of small size for micro scale robotic or mechatronic operations.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
