摘要
针对水下声波探测对低频、高灵敏度电化学水听器的需求,该文利用多物理场耦合分析软件COMSOL仿真分析电化学水听器敏感结构流道长度,阳极、阴极通孔直径,阳极、阴极孔间隔对其频率特性和灵敏度影响。仿真结果表明,流道长度对水听器的幅频特性和灵敏度影响相对不明显;随着阴极通孔直径的增大,水听器灵敏度降低,而频率特性变化相对不明显;随着阴极孔间隔的增大,水听器灵敏度降低。上述结果为电化学水听器的结构和性能优化设计提供有效指导。
In response to the need for low-frequency,high-sensitivity electrochemical hydrophones for underwater acoustic detection,this paper uses the multi-physical field coupling analysis software COMSOL to simulate and analyze the flow channel length of the electrochemical hydrophone sensing structure,the diameter of the anode and cathode through-holes,and the spacing between the anode and cathode holes on their frequency characteristics and sensitivity.The simulation results show that the channel length has relatively little influence on the amplitude-frequency characteristics and sensitivity of the hydrophone;with the increase of the diameter of the cathode through hole,the sensitivity of the hydrophone decreases,while the change of frequency characteristics is relatively insignificant;with the increase of the interval between the cathode holes,the sensitivity of the hydrophone decreases.The above results provide effective guidance for the optimal design of the structure and performance of electrochemical hydrophones.
