摘　　要：建立了同振球型矢量水听器的物理模型,利用该模型研究了柔性元件对水听器工作频率、振速幅值和相移等性能参数的影响规律。结果表明:水听器尺寸一定时,柔性元件弹性系数越小,水听器下限工作频率越低,一般在零点几到几赫兹之间;柔性元件主要影响低频段振速幅值测量,且弹性系数越大,影响越大,而振速测量过程中由柔性元件引起的相移几乎为零,可忽略不计。A physical model of the vibrating sphere type vector hydrophone is established, and the flexible components influence on hydrophone frequency, vibration amplitude and phase shift performance parameters are studied by the model. The results show that when the hydrophone size is certain, the smaller elasticity of the flexible member, the lower limit on hydrophone lower working frequency, generally between a few tenths to a few hertz. Flexible components mainly affects the low frequency vibration velocity amplitude measurement, and the elastic coefficient is big, the greater the influence, and the phase shift caused by the flexible components in the process of velocity measuring is almost zero, negligible.
