Design Analysis & Experimental Set Up of Flexure Bearing

Flexure bearing is a new concept and used for precision applications such as Programmable focusing mechanism (PFM), linear compressor etc. These bearings are compact and inexpensive. A flexure bearing is designed for specific applications. These design can usually be done with the advanced design tool like FEA. With the advent of computers FEA has become the most suitable tool for the engineering analysis where the conventional approach is not suitable, geometric complexity are involved etc. This paper deals with the study of flexure bearings in linear compressor and makes FEA analysis on it to calculate equivalent stress and tries to optimize it. Using software's like CATIA and PROE, modelling of flexure bearing is done. Also make FEM analysis on it by using Ansys software. Gaunekar have made design calculation for flexure bearing to make appropriate model. This bearing contains three spiral slots having 120° apart and 12 peripheral holes are used to clamp the disc rigidly onto a support structure. One central hole made for movement of shaft.
