摘要
利用有限元软件仿真设计了一种1-3型球形压电陶瓷复合材料换能器。采用切割-灌注-成型的方法,制备了1-3型球形压电陶瓷复合材料。利用研制的1-3型球形压电陶瓷复合材料制作球形换能器,并进行性能测试。结果表明,换能器的最大发射电压响应可达156 dB,-3 dB波束角可达44°,可实现高频宽波束发射。
A 1-3 spherical piezoelectric ceramic composite transducer was designed by using finite element software.1-3 spherical piezoelectric ceramic composites were prepared by cutting-pouring-forming method and their properties were tested.The spherical transducer is made of 1-3 spherical piezoelectric ceramic composite material and measured by the test system.The results show that the biggest transmitting voltage response of the transducer can reach 156 dB,and the-3 dB beam angle can reach 44°.It can realize wide beam transmission in the working frequency range.
