Calculating Flexure Hinges

A flexure hinge is an ideal construction element for making small angular rotations, without play and without friction. Material stress, angular rotation and required force are difficult to optimize without proper calculations. The free FlexHinge software application enables you to quickly calculate the stiffnesses and material stress of a flexure hinge. It carries out all calculations automatically. Simply fill in the material data and dimensions on a clearly laid-out window. The results will appear almost instantaneously in the same window.

Useful Results for Designers

You can use the results from FlexHinge directly in your design decisions. The calculations of the stiffnesses and material stresses in FlexHinge are based on the empirical formulas as given in the lecture notes “Het voorspellen van dynamisch gedrag en positioneernauwkeurigheid van constructies en mechanismen, W. van der Hoek 1981”. These are based on accurate FE-analyses. Read more about about FlexHinge in the article Flexure hinges: theory and practice.
