Title: Research on the Influence of Vibration Environment on Acoustic Performance of Hydrophone
Abstract: The hydrophone installed on the platform is the core component of the sonar equipment, and the surrounding vibration environment has an impact on the acoustic performance of the hydrophone at all times. There are two main ways for the vibration and noise of the platform to affect the hydrophone: one is that mechanical vibration is transmitted to the sensitive components of the hydrophone through the platform and the installation structure, which belongs to the direct transmission of vibration; the other is that the bending wave propagates along the platform to the vicinity of the hydrophone, which stimulates the flow around the hydrophone to produce the pressure wave decaying along the normal direction of the platform. In this paper, the influence of vibration excitation on the acoustic environment and voltage output performance of hydrophone with different structure and different installation state is studied by simulation modeling, the research results can provide references for hydrophone design and array.
