基于船舶-流场耦合作用的内河航段船舶航行虚拟辅助驾引OA北大核心CSTPCD

[Objective]In order to improve the safety of ship navigation,this study focuses on virtually aided ship navigation strategies.[Methods]Two different inland river routes are chosen for the simulation of virtually aided ship navigation models based on the fluid-structure interaction mechanism,while taking the navigation rules and flow details of the rivers into consideration.The simulation of the ship sailing process on a typical inland river route under specific current conditions provides the corresponding virtually aided naviga-tion plan in which the ship's velocity,location and course are obtained in a timely manner.[Results]It is found that the simulation method established on the basis of Fluent can be used to solve the problems of multi-degree-of-freedom motion and fluid-structure interaction.When sailing through bends or branches,steering with a small rudder angle over long distances ensures safe navigation and prevents speed reduction and signi-ficant lateral displacement.[Conclusion]The proposed method can be effectively combined with the flow field information of digital channels to simulate the ship sailing process,thereby providing data support for the decision-making of intelligent navigation on inland river routes.
