Simulation and Design of Portable Underwater Acoustic Transducer Test Device

Abstract:

In this paper, a portable underwater acoustic transducer sensitivity test device is designed to overcome the disadvantages of traditional test methods, such as the bigger size of anechoic pool, and single function of the vibrating column of liquid method. This new design has the advantage of small size, easy to carry and implement. A model of this device is constructed based on the finite element analyse software COMSOL Multiphysics. By calculating the sound field distribution of the test device model, the optimization size of the piezoelectric ceramic can be determined. Also the effect of some other key parameters, such as the material of vessel and thickness, are considered. All these results can provide the theoretical basement of the design of portable underwater acoustic transducer in practice.
