Review of circular flexure hinge design equations and derivation of empirical formulations

چکیده
This article presents the comparison of various compliance/stiffness equations of circular flexure hinges with FEA results. The limitation of hese equations at different t/R (R is the radius and t is the neck thickness) ratios are revealed. Based on the limitations of these design equations, a uideline for selecting the most accurate equations for hinge design calculations are presented. In addition to the review and comparisons, general mpirical stiffness equations in the xand y-direction were formulated in this study (with errors less than 3% when compared to FEA results) for wide range of t/R ratios (0.05 ≤ t/R ≤ 0.8). rown Copyright © 2007 Published by Elsevier Inc.
