Theoretical and experimental investigation of performance characteristics...

Cross-spring pivots have been widely employed over the last decades in a broad variety of precision engineering applications due to the high motion repeatability achieved thanks to the absence of stick slip and clearance. In this paper, the non-linear effect of the anticlastic curvature of the leaf-springs...

detasFLEX - a computational design tool for the analysis of various notch...

A novel computational design tool to calculate the elasto-kinematic flexure hinge properties is presented. Four hinge contours are implemented. It is shown, that FEM results correlate well with the analytical design tool results. For a given deflection angle of 10° and a corner-filleted contour, the...

Modeling and design of flexure hinge-based compliant mechanisms

aus: Kinematics
A compliant mechanism gains its mobility fully or partially from the compliance of its elastically deformable parts rather than from conventional joints. Due to many advantages, in particular the smooth and repeatable motion, monolithic mechanisms with notch flexure hinges are state of the art in numerous...

Contour-independent design equations for the calculation of the rotational...

Flexure hinges are often used as revolute joints in high-precision compliant mechanism, but without simulations the accurate prediction of their contour-dependent deformation and especially planar motion behavior is a challenging task. This paper presents contour-independent general design equations...

Analytical model of conductive graphite foam based sensors characteristics

Sensors play an important role in the control systems, because they provide the necessary information from surroundings to the controller of an automated systems. Today’s sensors are very sophisticated, with high accuracy, fast acquisition rate and good signal-to-noise ratio. But most of these sensors...

On the influence of the flexure hinge orientation in planar compliant mechanisms...

This paper presents the investigation of specific geometric parameters of planar compliant mechanisms with flexure hinges. The main focus is on the geometrical orientation of the flexure hinges and the form of the link connections between them. The synthesis of the compliant mechanism using a selected...

General design equations for the rotational stiffness, maximal angular...

Notch flexure hinges are often used as revolute joints in high-precise compliant mechanisms, but their contour-dependent deformation and motion behaviour is currently difficult to predict. This paper presents general design equations for the calculation of the rotational stiffness, maximal angular elastic...

Einfluss der Festkörpergelenkkontur auf die Bewegungsgenauigkeit und die...

Aufgrund ihrer Vorteile werden nachgiebige Mechanismen vielfach für Führungs- und Übertragungsaufgaben in Präzisionsbewegungssystemen eingesetzt. Hierbei werden vorwiegend prismatische Festkörpergelenke mit Aussparungen als stoffschlüssige Drehgelenke verwendet. In diesem Beitrag wird das Potenzial zur...

Model-based design of flexure hinges for rectilinear guiding with compliant...

Flexure hinges are often used in precision systems because in addition to other advantages they allow the simple adjustment of a required deformation and motion behavior of monolithic compliant mechanisms by geometrical design. In this contribution, the potential of improving the motion precision as...
