Design and performance analysis on flexible hinged magnifying mechanism applied to piezoelectric piling-up pump

A kind of flexible hinged magnification mechanism applied to piezoelectric piling-up pump was developed in this paper.The influences on the output displacement of the flexible hinged magnification mechanism affected by some main parameters of mechanism were analyzed through the finite element method,and the optimization design was carried out on the parameters.Taking this as a base the prototype was fabricated by machining,and its nice displacement magnifying function and characteristics of dynamic response were verified by means of experiment.
