Abstract: In this paper,the design of the flexure hinge positioning system having a relative wide range is studied.The paper gives the calculation and formulas for designing the flexure hinge. The flexure hinge mechanism amplified by a two step lever is achieved. It is shown by experimental results that the resolution of the precise positioning system is higher than 0.5μm and that the adjusting range is 180μm,In addition,the paper also discusses the driving property of a piezo-electric actuator used in the flexure hinge machanism.

Key words: lever amplification, flexure hinge, precise positioning
