Abstract
The ANSYS finite element analysis model for circular piezoelectric resonator is built in this paper, and experiments are carried out for verifying the validity of the finite element model. The influence of the piezoelectric resonator's fixation ways on the natural frequencies and vibration displacement is discussed, lower natural frequencies and higher efficiency of converting electric energy to kinetic energy will be gotten in the box fixation way. The researches on this paper provide a theoretical basis and effective ways for piezoelectric resonator design and optimization.
