Multiple Impact-Icebreaking Simulation and Structural Damage Research of Icebreaker
The risk of accumulated damage threatens the safety of icebreakers in multiple impact-icebreaking.A new sea ice material model suitable for ship ice collision has been adopted.According to the icebreaking scenario of the icebreaker,the scenario of reversing and then breaking ice by collision and breaking ice by multiple collisions is dynamically simulated.Compared with the single impact-icebreaking,the dynamic response characteristics during the multiple impact-icebreaking process are studied.The collision forces,damage and energy absorption laws of the bow structure are summarized,which can promote the design of icebreakers.
