摘　　要：极地船舶在行驶过程中发生碰撞会导致船体结构造成损伤,严重威胁船舶的生命力,因此提高船舶的抗碰撞能力对极地勘探及运输发展具有重大意义。针对传统加筋结构难以进一步提升其吸能效率,提出一种新型帽形结构。基于船舶碰撞理论和有限元数值方法,分析了舷侧的能量吸收-撞击深度曲线和破损情况,总结了不同结构的耐撞性能。结果表明,当撞击船的量级比被撞船大时,被撞船的破坏模式以压溃为主。在不增加结构重量的前提下,将常规舷侧结构改良为新型舷侧结构后,舷侧结构的防撞性能会大幅提高。极地船舶舷侧上有封闭区域可以提升舷侧的防撞性能。结果可为极地船舶结构设计提供一定的参考。Collisions between polar ships during navigation can cause damage to the ship's structure and seriously threaten its vitality.Therefore,improving the ship's collision resistance is of great significance for the development of polar exploration and transportation.A new hat shaped structure is proposed to address the difficulty of further improving the en-ergy absorption efficiency of traditional reinforced structures.Based on ship collision theory and finite element numerical method,the energy absorption-impact depth curve and damage situation of the hull were analyzed,and the collision resist-ance performance of different structures was summarized.The results indicate that when the magnitude of the impact ship is larger than that of the collided ship,the damage mode of the collided ship is mainly crushing.Without increasing the weight of the structure,improving the conventional side structure to a new side structure will significantly improve the collision res-istance performance of the side structure.The enclosed area on the side of polar ships can improve their collision resistance performance.The results can provide a certain reference for the structural design of polar ships.
