| Abstract: | A fluid structure coupling is raised by the interaction of a submerged moving structure with the fluid around.By use of MORISON formula,added water mass is calculated.The natural frequencies and modal characteristics of structure are obtained after considering the influence of fluid structure coupling and the dynamical response of structure is given also. |

| Keywords: | fluid structure coupling added water mass natural frequency dynamic response |
