悬浮式反鱼雷深弹的矢量水听器设计

Design of Vector Hydrophones for Suspended Anti-torpedo Depth Charge

为实现对来袭鱼雷的拦截,文中对悬浮式反鱼雷深弹可能采用的柱形矢量水听器进行了设计。首先,以刚性摆动柱形接收器声波接收响应模型为基础,推导了同振柱型矢量水听器的测量原理;通过计算机仿真,分析了采用压电加速度计的同振柱型矢量水听器相关参数的相互影响关系;最后选取设计了满足悬浮式反鱼雷深弹使用需求的矢量水听器技术性能参数。研究表明,在灵敏度和相位差条件允许的情况下,适当放宽对声学刚性运动柱体的几何尺寸要求,有利于悬浮式反鱼雷深弹中的同振矢量水听器的设计。

A cylindrical vector hydrophone for suspended anti-torpedo depth charge was designed to achieve the interception of an incoming torpedo. The measurement principle of a co-oscillating cylindrical vector hydrophone was derived based on the receiving and responding acoustic wave models of a rigid cylindrical swing receiver. The interrelationship among the parameters of a co-oscillating cylindrical vector hydrophone which uses piezoelectric accelerometers was analyzed by simulation. And the vector hydrophone′s technical performance parameters were selected and designed to meet usage requirements of the suspended anti-torpedo depth charge. Simulation results show that in the allowances of sensitivity and phase difference, less strict geometrical dimension requirement of the acoustic rigid moving cylinder may facilitate the design of the co-oscillating cylindrical vector hydrophone of suspended anti-torpedo depth charge.
