摘要:
阐述了Janus-Helmholtz换能器宽带工作的机理,运用有限元软件ANSYS对Janus-Helmholtz换能器的结构参数进行优化设计,研究了腔体结构尺寸对工作带宽等电声参数的影响规律.设计制作了一个工作带宽为500~2 000 Hz的试验样机.水池测试结果显示,仿真结果和实验结果基本相符.验证了有限元仿真结果的正确性,表明有限元方法是研究液腔振动和设计宽带Helmholtz换能器的可信手段.

Abstract:
The mechanism for broadband operation of Janus-Helmholtz transducer are described , the structure parameters of Janus-Helmholtz transducer are optimized using finite element software ANSYS and variation on operating bandwidth with the size of cavity wall are investigated . An experimental prototype of bandwidth of 500Hz-2000Hz is produced . Test results show that the simulation results agree with the experiment results. It shows that the finite element method is a trusted means on the study of cavity vibration and the design of broadband Helmholtz transducer.
