The Analysis of Cymbal Transducer's Frequency Characteristics Based on 1–3 Piezocomposite

Abstract

The frequency characteristic of Cymbal transducer based on 1–3 piezocomposite was analyzed with finite element analysis method in this paper. 1–3 piezocomposite was used as piezoelectric phase instead of piezoelectric ceramic and the brass foil was used as end cap. The mathematic model of this new type of piezocomposite transducer was established. Using ANSYS software, investigated the resonance frequency and the first, the second and the third order vibration models of this new piezocomposite structure. Fabricated the sample of Cymbal transducer based on 1–3 piezocomposite. Tested the first, the second and the third order of resonance frequencies of the transducer. The result showed that the theoretical value based on ANSYS is well agreement with the test result.
