摘　　要：在双向航行极地船舶的基本设计与线型优化阶段,需要对艉部先行模式下的冰阻力进行可靠的试验预报。吊舱与螺旋桨对艉部船-冰作用存在影响,但现有试验规程尚未合理考虑在该影响下船舶冰阻力的变化。以中国双向航行极地科考船“雪龙2”号为原型开展冰水池模型试验,对艉部先行模式下连续破除平整冰的过程进行了模拟。通过水上-水下联合摄录设备观测了船尾前冰层的破坏现象,并描述了螺旋桨对艉部船-冰作用的影响;结合艉部先行试验数据,提出了艉部先行模式下确定冰阻力的推荐方法,为艉部先行模式下的船舶冰阻力试验预报提供指导。To assist the basic design of double-acting polar ships,developing a reliable experimental prediction for the ship resistance in ice under stern-first mode is necessary.However,due to the influence of pods and propellers on the hull-ice interaction in stern area,the existing test procedures barely consider the change ofice resistance under this influence of rotational speed.Regarding this issue model tests in ice tank were carried out in this paper,and the continuous breaking of level ice under stern-first mode was simulated.During the test,the ice sheet failure in front of the stern,as well as the influence of propellers on the hull-ice interaction,was observed by underwater cameras.Finally,combined with the test data,the determination method for the ice resistance under the stern-first mode was proposed and discussed,thereby providing guidance for the prediction of stern-first ice resistance in the basic design stage.
