摘要
分别建立了船舶和冰排的有限元模型,采用LS-DYNA进行了碰撞接触计算,模拟了船首与冰排发生碰撞。主要考虑相同条件下分别改变冰排厚度、运动状态等单个碰撞参数,对比研究了不同碰撞工况下船舶的损伤变形、碰撞力等结构响应差异。得出了上述因素对船-冰碰撞的影响规律,为提高船舶抗冰载荷设计提供参考。
The FEM models of ship and ice floe are established and ship-ice.floe collision is simulated by LS-DYNA. By changing the thickness and the motion state, different structural dynamic responses of damage deformation of the ship and collision .force under different conditions are carried out. The influence rule of the above factors is obtained by comparing the different structural responses, which provides reference for anti-ice load structural design of ships.
