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.
Abstract
This article analyzes the turning maneuverability of polar navigation vessels.Firstly,based on the basic the-ory 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 resist-ance 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 pro-cess were analyzed.
