Ansys-based Finite Element Analysis of 0-3 Model Piezoelectric Vibrator

The 0-3 model piezoelectricity compound material is widely used for its flexibility,easy-to-fabricating and simple process.In this paper,the 0-3 model piezoelectricity compound material was used as the piezoelectric body of the piezoelectric vibrator in the piezoelectric cantilever.The effects of the parameters of the piezoelectric vibrator on the power-generation capacity and the resonance frequency have been analyzed through the Ansys-based finite element analysis including the static and modal analysis of the piezoelectric vibrator.The power-generation capacity of the vibrator is proportional to the force and the length of vibrator,inversely proportional to the width of vibrator,there exist the best length and thickness specific ratio between the piezoelectric cantilever.The natural frequency of the vibrator is inversely proportional to the length of vibrator and the mass of the mass bulk.The width has less influence to the natural frequency.These data provide designing reference for the structure parameters of the piezoelectricity cantilever.
