矢量水听器标准装置水声低频计量应用研究

摘要

It is expounded the calibration system of vector hydrophones apply to low-frequency un-derwater sound metrology, and introduced the metrology theory for two class hydrophones of the low-fre-quency underwater sound. It is proved that the feasibility of calibration system of vector hydrophone apply to the traditional hydrophones throught the suitable object, performance and measurement data of the two system. This is very importance and significance to make full use of the equipment resource.%对矢量水听器标准装置在水声低频计量中的应用进行了研究，简要介绍了水声低频计量中矢量、传统压电陶瓷两种类型水听器的测量原理，对矢量水听器标准装置和低频水声计量标准装置的适用对象、性能特点进行了分析和比较。通过现场实测数据，对矢量水听器标准装置用于传统压电陶瓷水听器低频校准的可行性进行了论证。论证结果表明，该矢量水听器标准装置除了可以用于矢量水听器的校准，也适用于传统压电陶瓷水听器的测试或校准，可以弥补低频水声计量标准装置受被测件最大尺寸局限的不足。
