Piezomotors using flexure hinged displacement amplifiers

IEE Colloquium on `Innovative Actuators for Mechatronic Systems', 1995
The design and construction of two different piezomotors developed by the authors is briefly described. Both employ flexure hinged mechanical displacement amplifiers to increase the output movement of stack-type piezoelectric actuators to enable them to be applied to rotation generating mechanisms. The first example is a harmonic piezomotor.

Displacement loss of flexure-hinged amplifying mechanism

The Proceedings of the Multiconference on "Computational Engineering in Systems Applications", 2006
The amplifying factor is utilized to study displacement loss of flexure-hinged amplifying mechanism in the paper. Firstly, the amplifying factors of three typical amplifying mechanisms are theoretically calculated. Then, the actual amplifying factor of lever-type amplifying mechanism, which is widely used, is detailedly simulated by using parametric ...

Micropositioning System with Flexure Hinges for Microfactories

Key Engineering Materials, 2013
In this paper it is presented a ductile system for micropositioning in a two-dimensional coordinate system. Accuracy positioning results from usage of asymmetric flexure hinges. It also it is presented the modeling of the asymmetric flexure hinges, finite element analysis, and experimental work.

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.

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.

Calculation and analysis of parabolic flexure hinge

Proceedings of 2012 International Conference on Measurement, Information and Control, 2012
Flexible hinges are widely used in micro robotic. Its compliance directly influences an organization's termial localization. Based on the Castigliano's second theorem and calculus, closed-form equations are formulated for compliances of parabolic flexure hinge. Precision of rotation is also evaluated in terms of compliances. The finite element analysis
