Research on the maneuverability of ship navigation in polar region
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.
