Development and evaluation of a new piezoelectric stick-slip actuator using stair type flexure hinge
Journal of Intelligent Materials Systems and Structures, 2022A new piezoelectric stick-slip actuator using stair type flexure hinge is proposed and developed in this work. It’s spirited by referencing the reported “Z-shaped” flexure hinge in the literatures and the idea of asymmetric structure. In this design, the

This paper designs and analyzes the hybrid flexure hinge composed of half a hyperbolic flexure hinge and half a corner-filleted flexure hinge. As it is transversely asymmetric, it has different performance when the fixed and free ends switch.

Proceedings. 2005 IEEE Networking, Sensing and Control, 2005., 2005
The paper introduces two hybrid flexure hinges: right-circular corner-filleted (RCCF) and right-circular elliptical (RCE) hinges. Closed-form compliance equations are formulated. Checked by the finite element analysis, the theoretical formulation data are within 8 percent error margins. The results indicate that the RCCF flexures have the best rotation-

Review of Scientific Instruments, 2015
Flexure-based mechanism like compliant actuation system embeds complex dynamics that will reduce the control bandwidth and limits their dynamic positioning precision. This paper presents a theoretical model of a leaf flexure hinge with damping layers using strain energy method and Kelvin damping model.

Review of Scientific Instruments, 1997
This paper presents closed form equations based on a modification of those originally derived by Paros and Weisbord in 1965, for the mechanical compliance of a simple monolithic flexure hinge of elliptic cross section, the geometry of which is determined by the ratio ε of the major and minor axes. It is shown that these equations converge at ε=1 to the

Design and stiffness analysis of a pitch-varying folded flexure hinge (PFFH)
, 2021Based on the theory and characteristics of the coil spring, we proposed a pitch-varying folded flexure hinge (PFFH), which is formed by a series of folded flexure units of variable pitches.

Corner-Filleted Flexure Hinges
Journal of Mechanical Design, 2000The paper presents an analytical approach to corner-filleted flexure hinges. Closed- form solutions are derived for the in-plane compliance factors. It is demonstrated that the corner-filleted flexure hinge spans a domain delimited by the simple beam and the right circular flexure hinge.

MEMS-Based Conjugate Surfaces Flexure Hinge
Journal of Mechanical Design, 2015This paper presents a new concept flexure hinge for MEMS applications and reveals how to design, construct, and experimentally test. This hinge combines a curved beam, as a flexible element, and a pair of conjugate surfaces, whose contact depends on load conditions.

Design calculations for flexure hinges
Review of Scientific Instruments, 2002This article presents design equations for calculating the compliance or spring rate of rectangular single-axis hinges and right circular hinges. The design equations are the result of an exact deduction and are concise in their expressions, so it is more convenient to use them in calculating and analyzing flexure hinges and flexure hinge mechanisms ...
