Modeling and design of an overlapped-flexure hinge for joule balance

Review of Scientific Instruments, 2019
In the joule balance experiment, the electromagnetic force and the gravity of the test mass should be aligned along the vertical direction precisely; otherwise, an alignment error will be introduced into the redefinition of the kilogram and the realization of the standard mass.

Optimized High-Precision Flexural Hinge Shapes

2006
Results of a strength-based optimisation of flexural hinge shapes are given. Both pre-defined and freeform parametric shapes are considered. By employing non-linear parametric optimisation algorithms, shapes that are best suited for the desired applications are determined.

Notch flexure hinges: An effective theory

Review of Scientific Instruments, 2002
This article presents effective tractable equations for rotational compliance (stiffness) of a simple monolithic flexure hinge with circular (radius R and crosspiece thickness t), elliptical [at semiaxis ax, ay, elliptical ratio ε (=ax/ay)] and other cross sections.

Accuracy Performances of Asymmetrical Right Circular Flexure Hinge

2011
Flexure hinge has been widely used in high precision micro-positioning mechanism driven by piezoelectric ceramic and the most common type is right circular flexure hinge. According to the size of the cutting arc radius of both sides of right circular flexure hinge, the structure coefficient is introduced and asymmetrical right circular flexure hinges ...

The construction and performance of various flexure hinges

Journal of Scientific Instruments, 1962
The first part of the paper describes a simple and yet precise clamp for strip hinges which facilitates the construction of flexure hinges. The use of this clamping system in various flexure hinges is described and it is believed that it is of fairly general application. The second part of the paper discusses the merits of the single strip hinge, which

Flexure Hinge Based Fully Compliant Prosthetic Finger

2017
A prosthetic hand is usually made by rigid body mechanism with ropes and pulleys. Such a hand is not “soft” to patients and nor to objects to be manipulated by the hand. In this paper, the concept of compliant mechanism is applied to a prosthetic hand.
