摘要
北极航区有大量冰山的存在,船舶航行时常会遇见与冰山的碰撞问题。基于安全考虑,着重研究北极航区船舶-小型冰山碰撞响应计算及损伤分析。利用Ansys/LS-DYNA软件建立船体和小型冰山的有限元模型,并进行两者碰撞的数值模拟分析。通过控制船速、吨位、碰撞角度等因素,在LS-PrePost后处理中得到船首各构件和小型冰山的损伤变形情况,以及船首结构能量时历曲线图和撞击力时历曲线图,并对该结果进行对比分析和讨论,得到船舶与小型冰山碰撞问题的研究结论,可以为冰区船舶设计提供一定参考。
There are a large number of icebergs in the arctic navigation area,and ships often encounter collisions with icebergs.Based on operational safety considerations,the study focuses on the collision response calculation and damage analysis of the ship-small iceberg in the arctic navigation area.The finite element model of the hull and small icebergs is established by using Ansys/LS-DYNA software,and the numerical simulation analysis of both collisions is carried out.By controlling the ship speed,tonnage,impact angle and other factors,the damage and deformation of various components of the ship’s hull and small icebergs,as well as the energy history curve of ship stern structure and the time curve of impact force are obtained in the LS-PrePost post-processing.Contrastive analysis and discussion were conducted on the results to obtain the conclusions of the collision between the ship and the iceberg.
