冰材料模型在船-冰碰撞结构响应数值仿真中的应用研究

摘要

In this paper, an ice material model is provided, which is applicable to numerical simulation of ship structure response under iceberg collision,. Based on this ideal ice model, numerical simulation of collision between ship and iceberg is carried out. The characteristics of dynamic response of ship structure under different collision angles of the iceberg are studied. The features of deformation, impact force and energy absorption by the ship under various conditions are revealed. The research provides a reference for ship design under ice induced loads.%提出适用于船-冰碰撞数值仿真研究的冰体材料模型。基于该模型，用非线性有限元软件对整船-冰碰撞进行数值仿真，研究船舶肩部与冰体在不同碰撞角度下发生碰撞时的动态响应特性，用以揭示不同工况下船舶损伤变形、碰撞力、能量吸收的规律，为船舶抗冰载荷设计提供参考。
