一种新型同振式矢量水听器的结构设计与性能研究

摘要

A new suspension system with central fixed is designed by studying the amplitude frequency characteristics of the piezoelectric accelerometer. The design scheme of the co- vibration vector hydrophone with the new suspensionsys-tem is presented, and its performance is simulated. The results show that the central fixed vector hydrophone has compact structure and convenient installation, which is suitable for the installation of the underwater small size platform. It canaccur-ately measure the sound pressure and particle velocity information in the working band.%本文通过分析压电加速度计的幅频特性,设计一种中心位置固定安装的悬挂系统,给出对应的新型同振式矢量水听器的设计方案,并对其性能进行仿真分析.结果表明,中心固定式矢量水听器结构紧凑、安装方便,适合水下小尺寸平台的安装使用,在工作频带内可准确测量声场中声压与质点振速信息.
