摘要
为了探究碎冰条件下冰区船试验方法和实船阻力预报方法 ,研究碎冰条件下冰区船舶阻力随速度变化规律,以及阻力随密集度变化规律,采用非冻结模型冰在拖曳水池中开展了4种密集度(60%、70%、80%、90%)工况下阻力试验。试验结果表明:随着碎冰密集度的增加,船模与碎冰的遭遇频率向更高速度点转移;碎冰密集度不同,船模总阻力不稳定区也不同;船模总阻力随着碎冰密集度的增加而增加;根据加拿大海洋技术研究所的Colbourne实船转换方法,预报了实船在1.05 m和2.0 m冰厚时的总阻力。
To explore test methods and the prediction methods of full-scale ship resistance for ships in the pack ice conditions and to research the laws of change in resistance versus velocity and resistance versus concentration,we carried out a resistance test using a model ship for four pack ice concentrations（ 60%,70%,80% and 90%） in a towing tank. The results show that the frequency of collisions between the model ship and the pack ice,and velocity increased with increasing pack ice concentration; different concentrations had different unstable regions of total resistance. The total resistance of the model ship increased with an increase in pack ice concentration. Finally,according to Colbourne＇s model-ship correlation at Institute of Ocean Technology,Canada,we forecast total resistance for ice thicknesses of 1.05 m and 2.0 m.
