| Abstract: | Starting with unique performances of Terfenol-D(Giant Magnetostrictive Materials,GMM),in combination with some new transducer design philosophies from home and abroad and aiming at the using characteristics of broad-band hydroacoustic transducer,this thesis specifies the theoretical design method and the structural form of hydroacoustic transducer.The test results and the service performance show that the anticipated goals are achieved.This is the domestically first application of such material in single broad-band hydroacoustic transducer and initiates another precedent for application of Terfenol-D. |
