The ice breaking capacity of the icebreaker depends on the geometric characteristics of the bow. Selecting reasonable bow configuration and characteristic parameters is helpful to improve the ice breaking capacity. In the ship parameters, the bow rake angle directly influences the ice breaking ability and the dipping efficiency. The ship collision with ice is simulated by using nonlinear dynamic analysis software LS-DYNA. By changing the bow rake angle, the collision force curves are obtained, and the ice breaking ability and efficiency of the polar ship with three bow configurations are calculated and compared with the ice resistance calculated by Riska formula. Through the analysis of the average longitudinal collision force and the ice breaking distance, the optimum bow configuration is selected. Combined with the calculation of the open water resistance, the scheme with the bow rake angle of 13 degrees is the best in the resistance performance.
