摘　　要：为了研究寒地海域航行实体靶船与浮冰发生碰撞过程中的载荷响应,基于S-ALE流固耦合方法和罚函数接触理论构建船-冰-水耦合的数值模型,展开冰-水耦合、船-水耦合以及船-冰-水耦合机理的研究,详细分析碰撞过程中产生的水阻力与冰载荷。结果表明,S-ALE方法在处理船-冰-水相互作用时可以较好地模拟碰撞场景。船体受载主要由水阻力与冰载荷构成,冰载荷占据主要成分。水阻力受到航速的影响,且水域对冰载荷起到了削弱作用;冰载荷随浮冰厚度、尺寸的增加而增加,浮冰尺寸的影响程度高于冰厚。In order to study the load response of full-scale target ship sailing in cold water during collision with floating ice,a numerical model coupling of ship-ice-water was constructed by the S-ALE fluid-solid coupling method and the penalty function contact theory.The mechanism of ice-water coupling,ship-water coupling and ship-ice-water coupling was studied,and the water resistance and ice load generated in collision processes were analyzed.The results show that the SALE method could simulate accurately of collision scene in dealing with the ship-ice-water interaction problem.The resistance of the target ship mainly includes water resistance and ice resistance,in which ice resistance occupies the main component.The water resistance is affected by the speed of target ship,and water domain would decrease the ice load.The ice load increases with the increasing of ice thickness and size,and the ice size has more effect.
