Abstract: Based on Fluid-Structure Interaction (FSI) model, the interaction between a plane wave and a shore-connecting ice plate was studied by using CFD method. Firstly, the numerical wave tank model was constructed to simulate the wave-making and wave-eliminating. The numerical results were compared with theoretical results to verify the accuracy of numerical water tank. On this basis, the shore-connecting ice plate was simplified as rigid and elastic plate, respectively, and interacted with the incident wave. The hydrodynamic forces were both obtained and the structural response of the elastic ice plate was obtained directly. On the other hand, the rigid ice was further assumed as a cantilever beam and its stress was obtained by adding the hydrodynamic forces on its surfaces. In this way, the responses between rigid and elastic ice plates were compared. The response characteristics of different ice models in waves were obtained, which was expected to provide references for ship navigation in ice zone from the perspective of external loads.
