- Abstract
Electroacoustic transducers as transmitters and receivers play major role in underwater communication systems. Piezoceramic rings are the most important parts of electroacoustic transducers. In this investigation, attempts were made to use the matrix model and the finite element model to evaluate frequency behaviour of piezoceramic rings. In order to validate the accuracy of the proposed models and the solution algorithm, results obtained from both models were compared with experimental results presented by Radmanovic, et al. Upon confirmation of the obtained results from the two models, the effects of the geometrical parameters on the frequency response of the ring and the surrounding domain in which the ring oscillates were studied. Based on the obtained results, the geometrical parameters have effects on both the frequency resonance of the ring, as well as the value of the electrical impedance. It is also noted that the surrounding domain only causes change on the intensity of the ring's electrical impedance.
