Topology Optimization of Flexure Hinges
2018This chapter is devoted to developing a systematic method for the topology optimization of flexure hinges. The main research work includes: (1) Developing basic topology optimization models for translational and revolute flexure hinges. The objective function for the topology optimization of flexure hinges is to maximize the compliance in the ...

Topology optimization of distributed flexure hinges with desired performance
Engineering optimization (Print), 2020Traditional notch flexure hinges have been widely used in precision engineering, but the lumped notch configuration limits the range of motion. This article presents a synthesis method for designing flexure hinges with distributed configurations using ...

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.
