摘　　要：破冰船在单个航次中多次冲撞式破冰可能造成船体结构累积损伤。为有效解决该问题,选用一种适合船冰碰撞研究的新型海冰材料模型,根据破冰船的破冰情景,对倒车后再次冲撞式破冰和多次冲撞式破冰的情景进行动态仿真。与单次冲撞式破冰进行对比,研究多次冲撞式破冰过程中的动响应特性,总结其中的碰撞力、结构损伤和能量吸收规律,为破冰船设计提供参考。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.
