Abstract

The flexural bearing is used for micro-machining and precision applications where low displacement is involved. It offers the advantage of almost frictionless, vibration free and maintenance free operation. The bearing element is deformed to provide desire relative motion between the surfaces. They are made up of deformable bodies called flexure. These flexures are to be designed for required displacement. However the analytical procedure for analysis of the flexure is not available. Hence, an alternative approach of using FEA is applied for design of flexure analysis. In this work flexure having different size and shape such as triangular, square, rectangular and elliptical are analyzed. The analysis of all the above shapes with various thicknesses for least axial, maximum radial stiffness and equivalent stresses is made. Later the results have been analyzed to choose optimum design of flexure.
