The invention discloses a ship motion model processing method and device and a storage medium, which can construct a ship motion response digital twin model in combination with environmental factors and optimize a ship motion response model in real time in combination with a motion parameter identification model so as to realize real-time accurate prediction of ship motion. The method comprises the following steps: acquiring a wind and wave flow state of a real environment in real time, and constructing an environment digital twinborn body according to the wind and wave flow state and a wind and wave flow mathematical model; according to the environment digital twinborn body, analyzing the environment disturbing force to obtain an analysis result; acquiring sensor data of a real ship, and constructing a ship motion model in combination with the motion parameter identification model; according to the analysis result, the ship motion model is simulated under real-time environment interference, and a ship motion state simulation result is obtained; according to the ship motion state simulation result, the error between the obtained ship motion state simulation result and the real ship motion response is smaller than a threshold value, and a ship motion response model reflecting real-time wind wave flow interference is obtained.
Description
technical field [0001] The invention relates to the field of ship motion models, in particular to a processing method, device and storage medium for a ship motion model. Background technique [0002] The parameters of the ship motion model are the core content of the modeling work in the navigation simulation. In the actual modeling process, the data is generally collected through real ship experiments, and then calculated after preprocessing, identification methods or empirical formulas. In related technologies, the parameter identification methods are mostly based on ship tank experiments or real ship observation data, and it is difficult to accurately predict ship motion responses under changing environmental conditions. Contents of the invention [0003] In order to solve at least one of the above technical problems, the present invention proposes a processing method, device and storage medium of a ship motion model, which can combine environmental factors to construct...
