摘要
建立破冰船破冰场景,基于流固耦合法进行数值仿真计算,分析水域流场对船体的冲击压力变化、流场的速度分布变化和流场的动能变化。将采用流固耦合法得到的计算结果与采用附加质量法得到的计算结果相对比,分析二者在船首的碰撞力大小、损伤变形和局部冰载荷等方面的差异,揭示流场对船-冰碰撞的影响规律。该研究对破冰船结构设计具有一定的参考价值。
The ship icebreaking scene is established.Based on the fluid-structure interaction method,the numerical simulation is carried out.The impact pressure of the water field on the bow,the velocity distribution of the fluid field and the kinetic energy of the fluid field are analyzed.Compared with the calculation results of the fluid-structure interaction method and the additional mass method,the differences of the collision force,damage deformation and local ice load of the bow are analyzed.The influence law of the fluid field on the ship-ice collision is revealed,which has some reference for the structural design of the icebreaker.
