中文摘要:
      针对同振型矢量水听器后期悬挂金属弹簧或橡胶绳给使用者带来不便的问题,提出一种中频同振柱型矢量水听器及其支撑结构的设计方案.通过矢量水听器振动系统对其声学特性进行分析,通过ANSYS有限元软件,利用Mooney-Rivlin理论对圆环形橡胶弹簧在压缩情况下的水平剪切刚度进行仿真计算,分析了Rivlin参数对橡胶弹簧剪切刚度的影响,并研制出矢量水听器样机.在1000~4000 Hz频率范围内,对矢量水听器进行了测试,并给出了测试结果.在1 kHz时,声压灵敏度为-195 dB,指向性凹点深度大于20 dB.测试结果表明,此种设计免除了反复悬挂金属弹簧或橡胶绳带来的负面效应.
英文摘要:
      Due to the inconvenience for users caused by the co-oscillating vector hydrophone using metal spring or rubber cords suspension, a design scheme of medium frequency co-oscillating cylinder vector hydrophone and its supporting structure is proposed. With the vibration system of acoustic vector hydrophone, the acoustic characteristics are analyzed. Using the finite element software ANSYS and the theory of Mooney-Rivlin, the horizontal shear stiffness of circular rubber spring is analyzed in the case of compression. The influence of Rivlin parameter on the horizontal shear stiffness of circular rubber spring is analyzed, and the acoustic vector hydrophone is developed. In 1000~4000 Hz frequency range, the hydrophone is measured, and the result is: the sound pressure sensitivity level is-195dB at 1 kHz and the ration of the maximum to the minimum in the directivity pattern is greater than 20dB. The measurement results show that the design method could reduce the negative influence of repeatedly suspending metal springs or rubber cords.
