| Abstract: | Analysis of the parasitic error sources can p ro vide a better design for the flexure hinge mechanism and decrease the cost. Geom etric errors of flexure hinges caused by machining imperfections are analyzed qu antitatively. The modeling and calculating errors of hinge motion by using simpl ified equations are evaluated. The assembling and fabricating errors to combine separated joints and links to a flexure hinge mechanism or a compound flexure jo int are discussed by modeling and plotting. The induced errors by vibration, the rmal and machining method are also predicted qualitatively. The effects of diffe rent error sources on the motion of flexure hinge mechanism are studied. Ways to improve the precision of micromanipulator are presented finally. |
