摘要：

Lever mechanisms are usually used to enlarge output displacements in precision stages. A precision stage employing a lever mechanism and flexure hinges is analyzed theoretically, with bending in the lever considered. Relations between design parameters and magnification ratio, and the optimal values for the parameters to achieve a longer stage displacement are presented. Finite element analysis is used to verify the theoretical analysis. It is found that adjustment of lever dimensions and hinge stiffnesses can increase the stage travel range significantly.
