【摘要】 本文针对极地航行船舶回转操纵性问题进行分析。首先基于操纵性基本理论，对船舶转舵阶段、过渡阶段以及最终回转阶段的回转操纵性运动方程进行补充和修正；进而采用重叠网格模型进行阻力仿真计算，并通过模型试验验证仿真模型的可靠性。最后基于DEM-CFD相结合的分析理论，对多组航行工况下船舶的浮冰区回转性能进行数值仿真，分析回转过程中的航行特点。更多还原

【Abstract】 This article analyzes the turning maneuverability of polar navigation vessels. Firstly, based on the basic theory of maneuverability, the motion equations of the ship′s turning maneuverability during the rudder turning stage, transition stage, and final turning stage were supplemented and modified; Furthermore, an overlapping grid model was used for resistance simulation calculation, and the reliability of the simulation model was verified through model experiments. Finally,based on the analysis theory combining DEM-CFD, numerical simulations were conducted on the turning performance of ships in the floating ice zone under multiple navigation conditions, and the navigation characteristics during the turning process were analyzed.更多还原
