| Abstract: | To avoid the complexity of the design in flexure hinge, one concise and accurate design method is presented for the one axis flexure hinge and a series of calculating equations of rotating rigidities of flexure hinge are deduced. Then the design method and the effect of the design parameters on the performance of one axis flexure hinge are discussed. In the end the application analysis of the one axis flexure hinge in a micro electro mechanical system (MEMS) is carried out through a design example of micro stage actuated by piezoelectric element, and the advantages of the method, time saving and high efficiency, are shown. |
