Preliminary Study on Maneuvering Motion Pattern of Unmanned Composite Trimaran Ship Model

Abstract:

The composite trimaran is characterized by adding the hydrofoils with different aspect ration in the main hull and sides of the conventional trimaran hull. Regarding the programmable automatic controller as the core, the paper designed the unmanned intelligent control system of the composite trimaran ship model, used VB.NET language to design the maneuverability simulation platform on MMG. And designed six rudder blades with different aspect ratio, and carried out a series of manipulation turning tests of the ship model under different speed and rudder angle. Through comparing with experimental data and the simulation results, it has verified the reliability of the simulation platform. Then with the system identification methods, the paper has discussed the aspect ratio of the rudder which has influence on the manipulation rotary motion of the composite trimaran ship model, and the manipulation rotary performance of the composite trimaran ship model in different speed and rudder angle.
