Design and Analysis of CombShaped Flexure Joint

doi:10.12068/j.issn.1005-3026.2014.09.023

Abstract

Abstract: A new combshaped flexure joint was proposed and designed in lamina emergent mechanisms. The equivalent stiffness of the combshaped flexure joint was deduced.Using theoretical calculation and finite element simulation analysis of the design example， the correctness of the calculation formula and simulation models was verified. Meanwhile， the equivalent stiffness could maintain a linear relationship even in large angular displacement. The strength of the example had been checked under the maximum angular displacement of the joint.Torsion stiffness of the joint was also simulated and analyzed. The bending stiffness of the example was compared among the combshaped flexure joint， ITLEJ joint and LET joint.

Key words: lamina emergent mechanisms, compliant mechanisms, combshaped flexure joint, equivalent stiffness, finite element analysis
