摘要

Mathematical model and 3D visual system are two key technologies of Fishing Vessels Simulator. According to MMG theory, a three-DOF manoeuvring mathematical model for fishing vessels is established, which can be used in ordinary-speed and low-speed fields. The model also considers the influences of wind and current. Based on Netherlands Ship Model Basin's open-water tests, Controllable Pitch Propeller model is achieved: firstly amends propeller's pitch, then by interpolating the results of B-serial propellers tests, gets propeller's four-quadrant thrust and torque coefficients under different pitches, finally gains the thrust and torque. Meanwhile, three control modes of CPP, including separated mode, variable-pitch mode and combinator mode, are realized. Comparisons between simulation results and sea-trial tests of a fishing vessel verify the model's rationality. To improve environment realism of system, a 3D-engine of visual system is developed with Scene Management Software, OpenGVS.
