【Abstract】 This paper has discussed the fabrication of bimorph flexural piezoelectric ceramic transducer and the resonance modes of metal piezoelectric bimorph transducers with a fixed boundary. We also use finite element analysis (FEA) to analyze the resonance modes of transducer. An advanced laser Doppler interferometer was used to measure and study the characteristics of transducer and also the distributions of the displacement and velocity of it. The results show that the zero load of the transducer is good and it is very useful for fabricating and analyzing transducers to combine FEA and advanced measurement tools.更多还原
