[Abstract]:With the development of ship design and propulsion technology, modern ship propeller adopts more dual propeller twin rudder ship propulsion, for this kind of manipulation and Research on propulsion performance is an important problem that has theoretical and practical significance. The establishment and manipulation of performance optimization this paper studies the problem of dual propeller twin rudder ship maneuvering motion model the application of virtual reality technology, virtual reality simulation of the dual propeller of ship motion, displayed the model of ship maneuvering motion performance. The main research work of this paper are as follows: (1) based on a kinematic model of ship data to establish a dual propeller twin rudder ship MMG control, were established on bare hull, the hydrodynamic force and torque mathematical model of propeller and rudder on, with the model of operating performance test. (2) based on the model , using particle swarm optimization algorithm of dual propeller ship maneuverability and propeller load optimization, reliability to improve the ship performance and cycle distance adjusting device, this paper analyzes the ship turning movement when turning circle parameters change and external load value. The paddle (3) digital simulation and virtual reality simulation of the dual propeller ship and propeller drive, digital simulation using Matlab/Simulink calculation model of ship motion information, including the ship position, speed, heading angle, while the numerical information in real time reflected in the ship model visual interface; virtual reality simulation by Vega API to obtain the ship motion parameters a ship motion virtual simulation system based on Vega platform, realizes the ship maneuvering as Jing Fangzhen also will be built on the 3D Max model optimized in Creator, The dynamic model of the DOF node is constructed to realize the 3D real-time animation demonstration function of the working principle of the wheel hub.
