摘　　要：近年来全球变暖的加剧使得北极航道的开放更具可行性,为分析极地船舶航行过程中的冰载荷及船体结构响应特性,本文针对船体舷侧结构与浮冰场多次碰撞的场景开展数值仿真研究。参考现阶段浮冰观测统计经验,建立船体舷侧结构-浮冰场相互作用有限元数值模型,在不同碰撞角度与不同浮冰密集度下开展仿真计算,分析船冰连续多次碰撞过程中碰撞力、能量及响应数据,研究碰撞角度和浮冰场密集度对浮冰载荷及船体舷侧结构响应特性的影响规律。结果表明,船冰多次相互作用下的结构响应规律与船冰单次作用存在一定差异,碰撞角度与浮冰场密集度参数对船冰碰撞力与船体舷侧结构响应特征影响呈现出一定的规律。本文研究内容对极地航行船舶舷侧结构的安全性设计具有参考价值。The intensification of global warming in recent years has made the opening of Arctic shipping lanes more feasible.In order to analyze the ice load and hull structure response characteristics during polar ship navigation,this paper carries out a numerical simulation study for the scenario of multiple collisions between the ship's outboard hull structure and the ice floe field.With reference to the statistical experience of ice floe observation at the present stage,a finite element numerical model of hull side structure-ice floe field interaction is established,and simulations are carried out at different collision angles and different ice floe densities to analyze the collision force,energy,and response data in the process of consecutive collisions of the ship and the ice,and to study the effects of collision angle and ice floe field densities on the ice floe loads and the response characteristics of the ship's hull side structure.The results show that the structural response law under multiple ship-ice interactions is different from that of single ship-ice interactions,and the impact of collision angle and ice floe field density parameters on the ship-ice collision force and hull outboard structural response characteristics shows a certain pattern.The research content of this paper has reference value for the safety design of the side structure of polar navigation ship.
