Claim 5:
6. The polar navigation window period assessment system based on three-dimensional visualization simulation of ship-ice interaction according to claim 2, wherein the Arctic navigation virtual scene module is used for calling the corresponding data in the database module, and obtaining a sea-ice collision load based on a contact point between a hull shell and the sea ice and in conjunction with a relative speed of a ship to ice, generating a sea ice breaking shape based on the sea-ice collision load and ice strength indexes, generating a plurality of pieces of broken ice randomly through circumferential cracking and radial cracking, and thus establishing the sea ice breaking process; establishing the ship-ice collision interaction based on physical attributes of the sea ice; analyzing ship resistance and structural response under sea ice based on a ship simulation model; assessing motion response of the ship in ice-water mixtures, and establishing the navigation virtual scene of the six-degree-of-freedom motion of the hull under sea ice based on a wave load, a sea ice load, and a ship weight load.
