Abstract

The work of this paper is aiming at a reasonable description or hypothesis of mechanical platform excitation of sonar array cavity on board the ship, which is necessary for comprehension of mechanism of the mechanical self-noise in sonar cavity. Through analytical deduction of the mechanical excitation transfer function between the source equipment and the sonar platform in a SPR (Source-Path-Receiver) system and corresponding numerical simulation, the excitation transmission characteristics is investigated. It is proved that weaker coupling between the solid sound propagation path and the sonar platform is essential for attenuation of sonar platform excitation. And in the condition of weak coupling, the excitation transmitted to the sonar platform is mainly dependent on the intrinsic vibrationmode of the solid sound path.
