摘要

This paper presents a model-based approach for designing flexure hinges with increased deflection. It will be shown, that the use of a polynomial function as notch contour allow increasing the hinge's compliance and the ratio of deflection to the maximum bending stress. This can be explained through analytical und numerical investigations and the comparison of polynomial contours with common notch shapes. Furthermore a possibility for simplification is presented which can help to facilitate mechanical manufacturing of these flexure hinges, based on the resulting polynomials. The advantages of using polynomial functions as hinge contours as well as the influence of the simplification is discussed with regard to the ratio of maximum bending stress to deflection.
