摘要
介绍了水下等离子体声源的产生机理和定向辐射方法,建立了基于ANSYS的旋转抛物反射面定向辐射装置仿真模型,采用拟合的冲击脉冲波形进行激励,进行了定向性能的分析和验证。结果表明,对于孔径280mm的抛物反射面,其定向增益可达14d B,定向性能良好。
The principle and approach of directional radiation of the underwater plasma sound source is introduced. The simulation model of a rotating parabolic reflector based on ANSYS is established, exciting with fitting impulse waveform, and the directional performance is analyzed and validated. For the parabolic reflector with aperture of 280ram, the directional gain is above 14dB.
