Generalized model for conic-V-shaped flexure hinges [PDF]

open access: yesScience 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]

open access: yesAdvances 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.

Design and performance comparison of double-series and triple-series flexure hinges

open access: yes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.

Shape Optimization for Flexure Hinges.

open access: yesJournal 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.
