Large stroke performance optimization of spatial flexure hinges [PDF]
, 2012 Flexure hinges inherently lose stiffness in supporting directions when deflected. In this paper a method is presented for optimizing the geometry of flexure hinges, while supporting stiffnesses are retained.

Design and analysis of a high-accuracy flexure hinge [PDF]
Review of Scientific Instruments, 2016 This paper designs and analyzes a new kind of flexure hinge obtained by using a topology optimization approach, namely, a quasi-V-shaped flexure hinge (QVFH). Flexure hinges are formed by three segments: the left and right segments with convex shapes and the middle segment with straight line. According to the results of topology optimization, the curve

Analysis and design of symmetric notch flexure hinges
Advances in Mechanical Engineering, 2017 This article presents the analytic models of four types of flexure hinges (elliptic, circular, parabolic, and hyperbolic flexure hinges). The analytic models are developed based on the theory of elasticity and infinitesimal method.

Fatigue testing of flexure hinges for the purpose of the development of a high-precision micro manipulator [PDF]
Mechanical Sciences, 2014 An approach was initially proposed for the estimation of the maximum von Mises stress in flexure hinges. It relied on recognizing relevant stress factors that were calculated from empirical functions set up by using the finite element method. Afterwards,

Shape Optimization for Flexure Hinges.
Journal of the Japan Society for Precision Engineering, 1997 The purpose of this study is to design an optimum profile of the flexure hinge with high axial stiffness and high bending flexibility. The conventional circular notched and rectangular notched profiles are not optimum because of low flexibility and high stress concentration.

Synthesis and Optimisation of Large Stroke Flexure Hinges [PDF]
, 2016 Flexure hinges are advantageous for use in high-precision applications because of their lack of hysteresis, friction and backlash. However, their range of motion is limited due to increasing stresses and a decreasing support stiffness at large strokes ...
