| 摘 要： | 声换能器的工作频带越宽,其所能发射和获取的信息量就越大。将目前热点研究的纵向振动换能器结构形式和换能器新型有源材料稀土超磁致伸缩材料加以结合,提出一种多谐振稀土纵向振动声换能器,通过理论分析,并应用ANSYS有限元软件仿真计算,实现换能器的小尺寸化,达到大功率超宽带发射的工作性能。

| Abstract: | The wider the frequency band of the transducer is, the more information it will transmit and obtain, which is the reason why the wideband is an important development direction of underwater acoustic transducer.The current hot spots of the longitudinal vibration transducer structure to be combined with the new active material Giant Magnetostrictive, a wideband rare-earth longitudinal vibration transducer is designed and developed with the purpose of achieving wideband,double-end radiation and high sound power performance with a compact size by taking use of the advantage of the transducer in structure and active material. |
