摘要

介绍了一种用于模拟破冰船在冰层中连续破冰的冰材料数值模型。通过与冰锥受压实验数据进行对比,对该数值模型进行了验证。将该模型应用于破冰船在无限冰区与冰层碰撞的数值模拟,对破冰船的破冰阻力进行了计算,并将不同船首、不同冰层厚度下计算所得的破冰阻力与经验公式计算结果进行了对比。

Abstract

Abstract:A numerical model of ice material was introduced for simulating the continuous icebreaking by an icebreaker in level ice.The numerical model was validated by comparing the numerical simulation results with the measured data in compressive cone-shaped ice experiments.The material model was applied to the numerical simulation of collision between the icebreaker and level ice in infinite ice field, and the icebreaking resistance was calculated.The results of numerical simulation and the icebreaking resistance calculated with different shape of bow and different ice thickness were compared with those by empirical formula.
