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 force requirements are difficult to optimize without proper calculations. The free FlexHinge software application allows you to quickly calculate the stiffness and material stress of a flexure hinge. It carries out all calculations automatically. Simply enter the material data and dimensions in an easy to use window. The results will appear almost instantly in the same window.

Useful Results for Designers

You can use the results from FlexHinge directly in your design decisions. The calculations of the stiffness 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.
