Large Ship Fluidsolid Coupling Dynamic Mathematic Model with Explicitly Form

In ship dynamics research field, large ship moving on sea water is a hot research project of water transportation. The fluidsolid coupling dynamics model of large ship is built by using time-dependent solid dynamics theory and fluid dynamics theory of ship. The linear analysis solution formula of ship deformation is obtained from the linear fluid-solid coupling equation. The hull displacements are obtained and the maximal displacement is found when the wave-hull resonance number becomes an integer.
