On mechanical properties of planar flexure hinges of compliant mechanisms [PDF]
Mechanical Sciences, 2011 The synthesis of compliant mechanisms yield optimized topologies that combine several stiff parts with highly elastic flexure hinges. The hinges are often represented in finite element analysis by a single node (one-node hinge) leaving doubts on the ...

Approximate equations for circular hinge stiffnesses
Nihon Kikai Gakkai ronbunshu, 2023 Flexure hinges are widely used for very high precision mechanisms, such as a high precision linear guide, a nano positioning stage, a robot hand and etc., because of no gap and no friction. Regarding circular hinge stiffnesses, Paros and Weisbord derived

Research on a Novel Flexure Hinge [PDF]
Journal of Physics: Conference Series, 2006 A novel single axis flexure hinge named hyperbolic flexure hinge is introduced as new designs in two-dimensional monolithic mechanisms. Based on the Castigliano's second theorem, Closed-form equations are formulated for compliances to characterize both the active rotation and all other parasitic motions.

New empirical stiffness equations for corner-filleted flexure hinges [PDF]
Mechanical Sciences, 2013 This paper investigates the existing stiffness equations for corner-filleted flexure hinges. Three empirical stiffness equations for corner-filleted flexure hinges (each fillet radius, r, equals to 0.1 l; l, the length of a corner-filleted flexure hinge)

Generalized model for conic-V-shaped flexure hinges [PDF]
Science Progress, 2020 This paper presents a new class of flexure hinges, namely, conic-V-shaped flexure hinges (CFHs), which can be used as a generalized model for flexure hinges with profiles such as parabolic-V-shape, elliptical-V-shape, and hyperbolic-V-shape. Compliance and precision equations for the CFHs were derived as a set of nonlinear equations using Castigliano ...

Parametrical Analysis of Elliptic Flexure Hinges [PDF]
Advances in Engineering Research, 2015 The model of parallel-oriented compliant mechanism was established. Analysis of parameters for elliptic flexible hinge plane compliant mechanisms was illustrated. The relationships between the system frequency and the flexible hinges shapes, geometry parameters, material parameters were discussed by numerical examples.
