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)

Design and performance comparison of double-series and triple-series flexure hinges
工程科学学报, 2017 The flexible hinge is one of the most important components in lamina emergent mechanisms (LEMs), so the design of a new type of lamina emergent torsional (LET) joint can play a key role in its movement performance.

Pseudoelastic flexure hinges in robots for microassembly [PDF]
SPIE Proceedings, 2000 The increasing tendency of products towards miniaturization makes the substitution of conventional hinges to flexure hinges necessary, since they can be manufactured almost arbitrarily small. On account of their multiple advantages like no backlash, no slip-stick-effects and no friction, their application is especially reasonable in high-precision ...

Fatigue damage stiffness degradation modeling of right circular flexure hinges
AIP Advances, 2023 Flexure hinges are susceptible to fatigue damage under cyclic loading, resulting in performance degradation. This paper investigates the stiffness degradation of the right circular flexure hinges (RCFHs) under cyclic loading.

Characterization of flexure hinges for the French watt balance experiment
EPJ Web of Conferences, 2014 In the French watt balance experiment, the translation and rotation functions must have no backlash, no friction, nor the need for lubricants. In addition errors in position and movement must be below 100 nm. Flexure hinges can meet all of these criteria.

Design and Performance Analysis of a Micro-Displacement Worktable Based on Flexure Hinges. [PDF]
Micromachines (Basel), 2022 The flexure hinge is a kind of micro-displacement adjustment device with application prospects because of its high displacement resolution, positioning accuracy and repeatability. In this study, a micro-displacement worktable with four degrees of freedom
