Evaluating Ice Load during Submarine Surfacing and Ice Breaking

At present, the calculation method of ice load on surface navigation ships has been very mature, but submarine is few. The reasonable evaluation become an urgent problem to be solved. In this paper, mechanical characteristics surfacing ice-breaking process are systematically analyzed. Based theory plate and shell, theoretical models resistance command tower hull established, respectively, obtained. Then, model SUBOFF used perform numerical simulation submarine’s process. result compared with model. results show that proposed in paper consistent results, influence parameters such as properties, upper area tower, initial crack length established. can provide a reference for optimization design polar structures.
