Analytical effects of design parameters on displacement of 2-DOF working platform employing bridge-type amplifier flexure hinge by finite element method

Abstract

The paper investigated effects of design dimension variables on displacement of a 2-DOF working platform employing bridge-type amplifier flexure hinge (BTAFH). The mechanism was created by the INVENTOR software and then obtained the output displacement (DI) by finite element method (FEM) in ANSYS. The FEM result indicated that thickness of flexure hinge (TOFH) strong impact on displacement of the mechanism and input body length contributed rising displacement according two axis x and y direction of the proposed model. The maximum value of displacement achieved 0.683 mm according x and y direction with input displacement of 0.01 amplified 68.3 times. This value is higher than the previous invest igatio n.
