Abstract：In this paper, dry and wet modal vibration of a ship is studied by finite element analysis based on the Ansys Workbench simulation platform. Then, the three-dimensional model of a 686 TEU multipurpose container ship is established by a ship modeling software. The model is introduced into the simulation platform to analyze the modal performance of a ship. Numerical calculation results show that the Workbench platform can be used to calculate the large structure mode by the fluid-structure coupling method and that it is feasible to use the fluid-structure coupling method to calculate the dry and wet modes of ship vibration in Workbench.
