Test mass alignment using overlapped-flexure hinge in NIM-2 joule balance
, 2020To solve the test mass misalignment problem in NIM-2 joule balance, a new suspension system with an overlapped-flexure hinge is proposed. The overlapped structure of this flexure hinge can guarantee the forces to act on the same pivot point, so the first

This paper presents a compact two-degrees of freedom piezo-driven positioning stage. To achieve large working stroke, the stick-slip principle was employed, and to make the stage compact, a lever-type flexure hinge mechanism (LFHM) with the L-shape ...

Lumped-Parameter Inertia Model for Flexure Hinges
Mechanics Based Design of Structures and Machines, 2004Abstract The article describes the analysis to derive the lumped-parameter inertia properties for variable cross-section flexure hinges for potential use in modeling, designing, and optimizing of these components in the resonant/dynamic range. Inertia fractions corresponding to one of the flexure's 6 degrees of freedom are formulated for single-, two-,

Space focusing mirror assembly with flexure hinges
SPIE Proceedings, 2014Focusing mirror assembly (FMA) is an important component of large space telescope. It can compensate the telescope's defocus caused by environmental factors. Telescope launching vibration and shock, as well as the structure stress of kinematic movement have great impact on focusing mirror assembly. To solve the problems of defocus result from vibration,

Notch flexure hinges: An effective theory
Review of Scientific Instruments, 2002This 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.

Piezomotors using flexure hinged displacement amplifiers
IEE Colloquium on `Innovative Actuators for Mechatronic Systems', 1995The 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.
