Finite element analysis of the cymbal-type flextensional transducer

摘要

The effect of material properties and dimensional changes on thenfundamental resonance frequency of the cymbal transducer has beenninvestigated using the ANSYS(R) finite element software. Vibration modenshapes, resonance frequencies, and admittance spectra for both air- andnwater-loading are calculated. Very good agreement is observed betweennthe modeled and experimentally measured admittance spectra in thenfrequency range up to 200 kHz, establishing the validity of the model.nThe calculations show that the fundamental resonance frequency can benmanipulated easily by changing the cymbal cap material or dimensions
