The underwater vibration characteristics of double plate with periodic connectors

Double plate is widely used to isolate the vibration and noise in the air,it needs more research on the underwater application.The vibration model of double plate with periodic connectors was built up.The transmission path of power was analyzed carefully and this analysis revealed the specific frequency and wavenumber selective characteristics of double plate in comparison with the single plate.The incident sound wave and the turbulence have very different frequency and wavenumber's spectrum,this may introduce very interesting usage in the sonar dome which needs consideration of both sound wave and turbulence.
