【摘要】 圆柱换能器阵是水声领域中常用的换能器阵之一,它采用压电圆管换能器沿着高度方向布阵而成。本文介绍一款可组合使用的圆柱换能器阵,子阵可单独使用,也可以组合使用。本文利用有限元方法对可组合圆柱换能器阵进行分析,并对其进行结构优化。所制作的可组合圆柱换能器阵的谐振频率为9.4kHz,最大发送电压响应156.8dB,最大声源级不低于208dB,水平指向性为全向,垂直指向性开角4.8°。更多还原

【Abstract】 The cylindrical transducer arrays are widely used for underwater applications,which adopt the piezoelectric cylindrical ceramic composed by the high direction.The combined cylindrical transducer array could be used by single or by double,which has been studied with finite element method.The finite element model of array is set up with ANSYS software and the structure of array is optimized.A final transducer array based on the above research achieves the radial resonance of 9.4kHz.The maximum of transmitting voltage response is equal to 156.8dB and the maximum of sound level is not less than 208dB,the horizontal direction is independent beam pattern and the vertical direction angle is 4.8°.更多还原
