In recent years, the polar navigation equipment is of increasing concern with the decreasing coverage and thickness of the arctic sea ice. Compared to traditional navigation areas, the sea ice will interact frequently with the ships in arctic regions, which is also one of the main causes of the fatigue damage of the hull structure. It is therefore of significant importance for the prediction of the dynamic structural response of ships sailing in Polar Regions to simulate the dynamic process of the ship-ice collision and analyze the influencing factors. The ice material parameters that can be applied to the commercial software LS-DYNA are proposed, with feasibility verification according to the P-A curve of ISO. The modeling of the bow is then established to simulate the collision between the bow and the floating ice under the operation conditions with bow speeds of 5kn, 6kn and 7kn, respectively, and a floating ice size of 10m×10m×0.6m, and then analyze the impact of the parameters.
