Abstract: In order to strengthen the bow strength of polar ships, this paper studied the ice conditions of polar routes, extracted the sea ice data of real polar routes and established the frequency spectrum table of ship sailing ice conditions. The full parametric design of the configuration of the ship's bow ensures that the bow can be freely deformed under the premise of smoothness. The idea of multi-objective linear programming was introduced in the eva-luation function, and an optimization model was established through an intelligent optimization algorithm. Finally, it established the optimal design method of the ship shape line with the best total income of the polar ship sailing in multiple ice conditions. The proposed method has a good effect on optimizing the ice-breaking capability of the bow under specific polar routes.
