| Abstract: | In this paper,a method for treating coupling boundary conditions with large movement,which include mobile inclined-plane and curved boundaries, is discussed for fluid-solid interaction dynamics and the nonlinear vibration of a 2-D floating rigid body on water surface is calculated.The available characteristics for the method is proved and it could be used to solve the problems of the real nonlinear vibration in which there are coupling boundaries with large movement for fluid-solid interaction dynamics. |
