This paper studies the dynamic characteristics of the rectangular ice cover and the related factors using the finite element method. First of all, the finite element model of the ice cover is set up according to the theory of displacement -pressure law which is used to solve the fluid-solid coupling problem, and the constraint conditions of the ice cover are simplified into two ways that are fixed constraint and space simply supported. Secondly it studies the relation between the modes of vibration and the constraints. Again this article analyzes the relation between the thickness of the ice cover and their frequencies. Finally the paper analyzes its natural frequency with different water depths under the action of the fluid-solid coupling.
