摘要

The present study examines the current research landscape of small ship electric propulsion, which is characterized by limited research content, challenging conditions for physical experiments involving propellers and ships, and the constraints of purely digital simulation methods concerning computational accuracy and efficiency. We simulate a small electric propulsion vessel equipped with a propeller using MATLAB-Simulink and conduct semiphysical simulation experiments to model the propeller and ship motion. These semiphysical simulation experiments are employed to analyze the propeller and ship motion model. The results demonstrate that the propeller simulation model and the Maneuvering Motion Group ship motion model developed in this study comply with the regulations established by the International Maritime Organization (IMO). Furthermore, the simulation model closely aligns with actual ship motion results, illustrating the principles of ship motion, with a simulation accuracy rate of approximately 90%, providing a clear solution for ship structure manufacture and design.
