Vibration reduction of floating elastic plates in water waves

Based on the dynamical theories of water waves and Mindlin plates, the investigation of the wave-induced responses and the vibration reduction of an elastic floating plate in water waves are presented by using the Wiener–Hopf technique. Firstly, without regard for the case of elastic connector, the calculated results obtained by the present method are in good agreement with the results from the literature and the experimental results. Therefore, it can be shown that the present method is valid. Secondly, the relations between the spring stiffness and the parameters of wave-induced responses of floating plates, which is used to connect the sea bottom and the floating plate's edge, are analyzed by the present method. Therefore, these results can be used as theoretical bases at the design stage of super floating platform systems.
