以极地运输船舶的首部作为研究对象，建立基于流固耦合算法的船-水-冰耦合技术对三维船首与冰体碰撞的结构响应问题进行研究，成功解决了船体、冰体与流场、船体与冰体之间的耦合，考虑了碰撞过程中船体与冰体的同步损伤，并结合非线性有限元软件Ls-dyna对比分析了冰体质量、船冰碰撞角度等撞击参数的结构响应问题，分析了不同碰撞工况下船舶撞击冰体后损伤变形、碰撞力等方面的变化特征，对分析船舶与冰体碰撞的结构性能具有参考价值。
The bow of the polar ships is choosed as the object of study. The ship-water-ice coupling technique based on the fluid-solid coupling algorithm is developed to study structure response of a three-dimensional ship bow and ice body collision and this paper successfully resolved the way of fluid-structure coupling and the ship-ice coupling. Considering the synchronous damage of the ship and the ice and the nonlinear finite element software Ls-dyna is used to study the collision between the bow with the different mass of ice and angles under the ship ice collision structure response of various schemes. Then, the simulation results reveal the features of the ship deformation, impact force on the collision of the ship and ice under various programs. All of above can also provide technical supports for the future ship-ice collision study.
