摘　　要：船冰作用力的预报是冰区船航行性能评估环节的重点。本文针对某冰区航行船开展操纵性斜航模型试验研究,采用以聚丙烯为主材的圆形非冻结模型冰,通过模型试验给出船在无冰水域和中高密集度浮冰区的船体受力,研究船体在不同航速和漂角下的船体受力特性,并基于典型工况分析试验数据的重复性,发展冰区航行船的非冻结模型冰模型试验技术。研究结果表明:浮冰密集度、航速和漂角的增大会使船体受力增大,高密集度和大漂角下船冰接触区域更大,试验数据重复性也较好。Prediction of ice force acting on the hull is a key to assess the navigation performance of ice-going ships.An ice-going ship was used to conduct the manoeuvring oblique test,the circular synthetic ice made of polypropylene was adopted,the forces of hull in water and medium and high floe ice concentration region were given by model test,the characteristics of force under different speeds and drift angles were investigat-ed,the data repeatability was analyzed based on typical conditions,and the synthetic ice model test technolo-gy was developed.The model test results show that increasing ice concentration,speed and drift angle will cause the larger force acting on the ship,the contact area of the ship and ice is larger in higher ice concentra-tion and larger drift angle,the repeatability of data is also better.
