矢量水听器测试模型及拾振条件探讨

The testing model and the condition commanded by vibration picking of a vector hydrophone

本文建立了矢量水听器的拾振模型,并分析推导了其拾振条件。首先从声学理论角度介绍了矢量水听器工作模型并得出矢量水听器的拾振条件,然后分别从声场分析的角度、振动学角度建立矢量水听器工作模型并得出相同的矢量水听器的拾振条件。即水听器波尺寸越小越好及水听器与水介质等密度的条件,另外矢量水听器与水介质质点之间悬挂系统的刚度越小越好。最后根据文献介绍的实测结果,分析了矢量水听器拾振条件的符合性。

The model of vibration picking for a vector hydrophone is established. The condition for vibration picking is deduced in various ways. First the method of analysis of acoustic field is used, then the theory of vibration. Finally the accordance of the condition of vibration picking with the experimental testing result given in an earlier paper is discussed.
