摘要
针对一艘在极地海域内以船艏破冰方式航行的运输船,进行了漂浮冰条件下船舶航行阻力的模型试验。试验测试以拖曳船体模型在冰水池内行进的方式进行,试验中对冰条件的模拟针对极地海域的当年生单层浮冰进行。试验观测针对多种船体航行速度、浮冰尺寸以及冰覆盖率展开,观测内容包括:浮冰与船体的相互作用模式、浮冰的破坏和运动模式以及船体航行总阻力。试验测试结果表明,船体航行速度对浮冰的破坏和运动状态具有重要的影响,船体总阻力在不同的冰覆盖率下具有显著的变化,这种变化规律又受到船体航行速度的影响而呈现出不同的趋势。
Model tests of the resistance of a transport ship, by the bow of which the ice can be broken, are carried out in an ice tank simulating single-layer ice in the current year in the Arctic region under pack ice condition. Observations include interaction between pack ice and ship, failure of the pack ice and its motion states, and total ship resistance. It is shown that the ship speed has a significant influence on the failure and motion status of the pack ice, and total ship resistance varies remarkably with different ice concentrations.
