针对1-3型压电复合材料换能器完整模型节点数多、计算时间长,周期模型不能直接模拟换能器水中响应特性等问题,提出了应用ANSYS软件分析1-3型压电复合材料发射器的方法,并利用此方法和厚度模式理论设计了1-3型压电复合材料发射器.同时对厚度模式理论及有限元法计算结果和试验结果三者做出了对比分析.研究结果表明,所采用的有限元法计算结果与测试结果吻合较好,制作的复合材料发射换能器谐振频率为300 kHz,最大发射电压响应为178 dB,且厚度模态纯净.
Aiming at the problems of 1-3 full-model piezoelectric composite transducer with large number of nodes, long calculation time and periodic model can not directly simulate the response characteristics of transducer, this paper presents the application of ANSYS software to analyze 1-3 piezoelectric composite materials Launcher method and the use of this method and the thickness mode theory 1-3 piezoelectric composite launcher was designed.At the same time, the thickness mode theory and the finite element method calculation results and the experimental results made a comparative analysis of the results of the study The results show that the calculated results agree well with the experimental results. The fabricated composite transducer has a resonant frequency of 300 kHz and a maximum response voltage of 178 dB. The thickness mode is pure.
