Design and nonlinear modeling of a large-displacement XYZ flexure parallel mechanism with decoupled kinematic structure

This article proposes an XYZ flexure parallel mechanism FPM with large displacement and decoupled kinematic structure. The motion range of the large-displacement FPM using notch hinges is more than 1 mm and is achieved by assembling the typical large-displacement prismatic joints and a new large-displacement prismatic joint proposed in this article. Moreover, the decoupled XYZ stage has small c...

Elastic Averaging in Flexure Mechanisms: a Multi-beam Parallelogram Flexure Case-study

Over-constraint is an important concern in mechanism design because it can lead to a loss in desired mobility. In distributed-compliance flexure mechanisms, this problem is alleviated due to the phenomenon of elastic averaging, thus enabling performance-enhancing geometric arrangements that are otherwise unrealizable. The principle of elastic averaging is illustrated in this paper by means of a...

A Study on Precision Stage with Displacement Magnification Mechanism Using Flexure-Based Levers

This study presents a precision stage driven by a piezoelectric actuator and equipped with a displacement magnification mechanism for the purpose of easy displacement measurement. The displacement magnification mechanism consists of flexible hinges and lever mechanisms. The developed stage is able to provide accurate measurement by virtue of the displacement magnification mechanism, but it is e...

Experimental induction of left abomasal displacement: a new educational technique

The purpose of this study was to induce abomasal displacement to the left, and to let the undergraduate and post graduate students get used to the ping sounds of abomasum and other clinical manifestations. The procedure was carried out on eight young bulls, they were sedated and a 2 m flexible tube was inserted through the nasal canal into the rumen. By laparo-rumenotomy, 20 cm of the tube was ...
