Abstract

Systems of recognition and location identification of underwater moving bodies which using acoustic waves are called sonar. Electroacoustic transducers have an important role in underwater communication systems such as Sonar. A set of electroacoustic transducers which is called sonar array, can be used for sending and receiving underwater sound. The most widely used transducer in these arrays are TONPILZ TRANSDUCER. In this paper, a full simulation of TONPILZ TRANSDUCER is given and the most important factors for evaluating transducer performance are checked experimentally and numerically. Also for validation of finite element model, the sample of transducer was designed and made. This transducer was tested in two methods, electrically and acoustically. Electrical behavior was tested by Impedance gain analyzer devise. Acoustic test was carried in the acoustic pool. Then the result of FEM compared with experimental results. With comparing FEM results and tested model, it is observed that the finite element model can predict electrical and acoustical behavior of TONPILZ TRANSDUCER so well. Finally it is tried to improve FREQUENCY RESPONSE of transducer with making changes in the structure. While the addition of damping factors can increase frequency bandwidth.
