摘　　要：随着越来越多的国家认识到北极地区巨大的潜在价值,冰区船舶的性能研究和设计工作也愈发的为人们重视。为了研究冰区船舶在碎冰区域内的航行阻力,运用Ls-dyna软件的罚函数算法和流固耦合算法对冰区船舶在碎冰中航行过程进行了数值模拟,分别计算了60%、80%和90%碎冰密集度下4个速度点的船-冰作用力。在船模拖曳水池非冻结模型冰试验的基础上,对数值模拟结果进行分析评估。认为数值模拟结果在较低速度条件下在定性上与试验结果比较符合,数值模拟方法在冰区船阻力性能研究工作中有着重要的参考价值。As more and more countries have recognized the huge potential value of the arctic,performance research and design work of ship in pack ice are drawing more and more attention of people. In order to study the ship resistance in the crushed ice area,this paper uses the penalty function algorithm and fluid structure interaction algorithm of ls-dyna software to carry out numerical simulation for the sailing process in crushed ice,and calculates the force between ship and ice at four speed points under 60%,80% and 90% of crushed icedensities. On the basis of nonrefrigerated ice model test in ship model towing tank,the results of numerical simulation is analyzed. The results of numerical simulation are in good accordance with the test results on qualitative level at low speeds. Numerical simulation method has important reference value for the research work of ship resistance in ice region.
