Abstract :
The basic principle of the equivalent beam methodology (EBM) is introduced and the performance of a double parallel four-bar flexure hinge mechanism is discussed. First, the displacement of this mechanism is theoretically analyzed. Then the displacements of mechanism are studied with the EBM and the conventional finite element method (CFEM) in software ANSYS. Compared with the analytic result of the CFEM, the EBM has the advantage of high efficiency with a low number of elements, which is very important for the simulations of micro-positioning stage with complex flexure hinge mechanism.
