Analysis on Displacement Performance Affected by Machining Errors of Single-Notch Right Circular Flexure Hinge

Abstract:

The output displacement error of the single-notch right circular flexure hinge caused by the machining errors is studied. Firstly, two kinds of factors of machining error in single-notch right circular flexure hinge is put forward, namely, the dimensional deviation of three basic parameters of flexure hinge and the angular deviation of the central line of notch-part circular arc. Then, the relationship between the factors of machining error and the output displacement of flexure hinge is analyzed using FEM software ANSYS. The analytic results demonstrate that the minimum thickness and the cutting radius of flexure hinge have strong influence on the output displacement while the results show the angular deviation of the central line of notch-part circular arc around the -axis has almost no influence on the output displacement. The analytical result has an important significance to design flexure hinge.
