中文摘要:
      应用六自由度数值模型对某破冰船的连续式破冰过程进行数值模拟,得到其冰载荷的时历,并将其与试验结果进行比较,验证该方法的正确性,同时分析冰载荷动态性变化的原因。通过计算得到破冰船在不同速度及冰厚条件下的冰载荷和运动响应,以及航速与船舶冰载荷之间的关系。
英文摘要:
      An icebreaker’s continuous icebreaking process is simulated with a numerical model of six degrees of freedom to acquire the ice load’s time series, which is compared with the results of trial to verify the validity of the method. The reason leading to ice load’s dynamic nature is analyzed as well. The ice load and motion response are calculated under different velocities and ice thickness to gain the relation between the velocity and the ship ice load.
