In this thesis, numerical and experimental design of a multi-frequency underwater acoustic transducer with cylindrical piezoelectric ceramic tubes is studied. In the numerical design, the acoustic, mechanical and thermal performances of the transducer are investigated by means of finite element method (FEM) in ANSYS. The design of the transducer that meets the acoustic requirements is checked in terms of the mechanical and thermal performances. After the completion of the numerical design, the transducer is manufactured and some performance tests such as impedance test, hydrostatic pressure test and full-power operation test are applied to it. Finally, the results of the numerical and experimental design are compared. As a result, the design of an underwater acoustic transducer that operates at two frequency bands centered at about 30 and 60 kHz under a hydrostatic pressure of 30 bars is accomplished. This transducer also resist to a shock loading of 500g for 1 millisecond.
