Compliances calculation and performance analysis of Half Circular-Elliptical Hybrid flexure hinges
A novel flexure hinge named half circular-elliptical hybrid flexure hinge was presented. Based on Castigliano’s Displacement Theorem, the compliance equations of the novel flexure hinge were formulated. A computer aided analysis and parametric design program of the half circular-elliptical hybrid flexure hinge was developed by VC++6.0. A specific half circular-elliptical hybrid flexure hinge wa...
متن کاملA Generic Compliance Modeling Method for Two-Axis Elliptical-Arc-Filleted Flexure Hinges
As a kind of important flexible joint, two-axis flexure hinges can realize in-plane and out-of-plane motions and can be used for constructing flexure-based spatial compliant mechanisms. The paper introduces a common two-axis elliptical-arc-filleted flexure hinge that is generated by two different elliptical-arc-filleted cutout profiles and that provides some new hinge types. The analytical comp...
متن کاملLarge Stroke Performance Optimization of Spatial Flexure Hinges
Flexure hinges inherently lose stiffness in supporting directions when deflected. In this paper a method is presented for optimizing the geometry of flexure hinges, while supporting stiffnesses are retained. These hinges are subjected to a load and deflected an angle of up to ±20°. The measure of performance is defined by the first unwanted eigenfrequency, which is closely related to the suppor...
متن کاملOptimal Design and Control of a z-Tilt Piezoelectric Based Nano-Scale Compensation Stage with Circular Flexure Hinges
The Taguchi method is widely used for the optimization of mechanical design and this study is used it in the design of a 2D circular flexure hinge for a z-tilt piezoelectric based nano-scale compensation stage. Maximum displacement of the stage is 16 μm at z-axis and ±30 arcsec at θx and θy. The most important design parameters for such a flexure hinge are minimal diameter, body height, and not...
متن کاملRevision of failed knee replacements using fixed-axis hinges.
Forty failed hinged arthroplasties of the knee were revised by the insertion of another hinged implant. In 14 cases the prosthesis used at the revision operation was similar to the primary implant; in 26, a hinge with an elongated femoral stem was used, usually replacing part of the femoral shaft. In seven of these knees an elongated tibial stem was also required, though the tibial shaft was re...
