摘　　要：通过模型试验探究气泡辅助系统降低船舶与碎冰相互碰撞的机理,依托“雪龙2”号船模设计了气泡辅助航行系统,在哈尔滨工程大学室外冰水池内进行了非冻结模型冰碎冰航道的船模拖航试验。通过机理试验,探究气泡辅助航行系统使用前后船模与浮冰相互作用模式的差异,同时根据船艏、船舯的浮冰清除效果,分析该系统对这两部分浮冰碰撞作用的减轻程度;随后改变试验参数,探究航速、喷气量以及浮冰密集度对该系统工作效果的影响,进一步探究该气泡辅助系统的工作机理。In this work,the mechanism of an air bubbling system to reduce the collision between ship and crushing ice was explored by using a model experiment.The air bubbling system was designed for the model of the“XUE LONG 2”,and the model experiment of simulating the crushing ice channel was conducted in the outdoor ice pool of Harbin Engineering University.Through the mechanism experiment,the difference of the interaction between the ship and the crushing ice was explored,before and after using the air bubbling system.Meanwhile,the impact of crushing ice on the bow as well as the midbody of the ship model was analyzed,according to the removal effect of the crushing ice away from the hull.On this basis,the effects of the speed,jet volume and ice concentration were investigated by changing the experimental parameters.
