A novel nanometric precision two-degrees-of-freedom positioner driven by PZT was designed and fabricated.The theoretical and experimental analyses of the stage performance were also done.The nanopositioning stage consists of a right-angle flexure parallel hinge to realize the motion along X and Y directions and the flexure pivoted lever arm to achieve piezoactuator displacement amplification. The differential equation of motion was established by Lagrange equation
and the expression of the two mode nature frequencies were derived. The model analysis of the stage was carried out by means of ANSYS
a Finite Element Method (FEM) code. Experiments were conducted to measure the modal frequencies of the stage. The results obtained from formulation
Finite Element Method(FEM) and experiments were analyzed. The numerical and experimental results prove the accuracy of the theoretical model and the validity of the FEM analysis.
