摘要
矢量传感器的测向输出结果会受到其安装结构散射声场的影响,而球形障板是矢量传感器工程应用中最为常见的一种结构。在分析球形障板散射声场的基础上,采用有限元和边界元相结合的方法,对弹性球形障板散射场进行计算,得出矢量传感器的测向结果随其安装位置和信号的入射频率变化的影响规律,最后通过水池试验对其进行了验证。
In engineering applications, the output of vector hydrophone will be influenced by the scattering field of the fixings. The scattering field of elastic spherical baffle is calculated with the method named FEM＋BEM, and the effect rules on direction-finding of vector hydrophone have been gotten and comfirmed by the pool lab in the end of this article when the fixing position and the signal＇s frequency are changed.
