| Abstract: | Based on the principles of fluid mechanics, the dynamics of structure and the variational principle, dynamic equations for the interaction between the structure and the fluid-the coupled system of structure-fluid, have been deduced. Thus, it provides the feasibility to carry out numerical analyses of the dynamic characteristic and response of a moving structure in the water. |

| Keywords: | coupling of structure and fluid addmass dynamic characteristic response |
