Research on dynamic ship domain model and simulation

With the research and development of ship intelligence, the ship domain as the key of intelligent collision avoidance technology, it is still the key theoretical basis for the assessment of the degree of danger of ship accidents, shipping safety, collision avoidance strategy, water passage capacity, and the overall planning and design of waterways. Modeling and simulation in the field of ships is one of the key technologies for future intelligent ships and intelligent collision avoidance. Based on the research literature of related experts and scholars, through the analysis and research of the existing ship domain model, it is proposed that the ship domain model has two important characteristics of dynamics and threedimensionality. By introducing the dynamic scale factor and considering the influence of relevant effects in the sailing process, the model is processed dynamically and three-dimensionally to establish a dynamic ship domain model. Using MATLAB as a simulation tool, a set of simulation program of dynamic ship domain model is designed based on the established dynamic ship domain model and applied to the ship crossing the Nanjing Yangtze River Bridge, which verifies the feasibility of the model and provides a reference for the future research on intelligent navigation and collision avoidance.
