Abstract
This paper presents the design and the specific analysis of a novel spatial symmetrical compliant mechanism with closed - loop subchains which is capable of driving the piezoelectric valve-less micropump in high frequence. This design of the topological configuration evolving from the bridge-type magnification mechanism amplifies the longitudinal deformation of the piezoceram actuators in parallel to the transverse displacement generation in dozens of times. In order to further estimate the performance of displacement amplification, the elastic beam theory, screw theory and the Pseudo Rigid Body Model (PRBM) are adopted to determine the ideal displacement amplification ratio. The FEM simulation is carried out to cross validate the design of the flexure-based mechanisms.
