本文采用数值仿真方法研究某PC4级油船在极地碎冰区航行时船首与浮冰发生碰撞时的动响应特性，考虑碰撞引起的冰-水耦合作用，分析浮冰形状及碰撞位置对船体结构响应、船-冰碰撞力特性的影响，研究不同碰撞工况下船体外板的应力分布和冰体破损特征，对油船极地冰区航行操作规程的制定及抗冰结构设计具有指导作用。
In this paper, the numerical simulation method was used to study the dynamic response characteristics of a PC4 oil tanker colliding with floating ice. Considering the ice-water interaction caused by collision, the hull structural response and collision force were analyzed by the influence of ice shape and collision position. The stress distribution of shell plate and ice damage characteristics under different collision case were studied. This research work can be of great significance for navigation rules formulating and hull anti-icing structural designing.
