Short summary
Notch flexure hinges are often used as revolute joints in high-precise compliant mechanisms. Therefore, this paper presents design equations for the calculation of the rotational stiffness, maximal angular elastic deflection and rotational precision of various notch flexure hinges in dependence of the hinge parameters and the load. Four flexure hinge contours are investigated, the semi-circular, the corner-filleted, the elliptical, and the recently introduced bi-quadratic polynomial contour.
