Elasto-Kinematics and Instantaneous Invariants of Compliant Mechanisms Based on Flexure Hinges [PDF]
Micromachines, 2023 The kinematic synthesis of compliant mechanisms based on flexure hinges is not an easy task. A commonly used method is the equivalent rigid model, which involves replacing the flexure hinges with rigid bars connected with lumped hinges using the already ...

Generalized model for conic-V-shaped flexure hinges. [PDF]
Sci Prog, 2020 This paper presents a new class of flexure hinges, namely, conic-V-shaped flexure hinges (CFHs), which can be used as a generalized model for flexure hinges with profiles such as parabolic-V-shape, elliptical-V-shape, and hyperbolic-V-shape. Compliance and precision equations for the CFHs were derived as a set of nonlinear equations using Castigliano ...

On mechanical properties of planar flexure hinges of compliant mechanisms [PDF]
Mechanical Sciences, 2011 The synthesis of compliant mechanisms yield optimized topologies that combine several stiff parts with highly elastic flexure hinges. The hinges are often represented in finite element analysis by a single node (one-node hinge) leaving doubts on the ...
