Modeling And Simulation For Ship Manoeuvering

With the rapid development of information technology, the application of Computer Simulation has been widely used in the field of electric power, nuclear energy, petroleum, chemical industry, transportation and navigation. Ship handing simulator is a typical example of Computer Simulation in the field of navigation, and has become an important way to train and examine sea going officers. The simulation for ship manoeuvering system is one kernel part of Ship Bridge Simulator.The project design is mainly about the modeling of ship manoeuvering and the studying of the connection between ship direction and rudder angle, so themodeling can be devided into two parts-the hydraulic system of the rudderand the dynamic equation for ship moving. The model of the hydraulic system and examing programs of the rudder is to realize the control of rudder and monitor the state data of the hydraulic system. The model of ship movement is to show the ship moving direction after the rudder deflextion, and monitor the state of shiphead direction during the course of the disturb of wind and flow.The simulation program of ship manoeuvering is developed on the platform of the universal operating system of Windows, utilizing Microsoft Visual C++ 6.0 , which offer a visible environment for develping program. Microsoft Visual C++ ,which is in agreement with the idea of modern software engineering, is an objected-oriented computer program language. By using Visual C++, the programmers can change the property of object flexibly according to different requirement. In the meantime, it also provide strong power for tracking variablesThe simulation program for ship manoeuvering realize the simulated control of ship, and real-time monitor the state of rudder and ship moving . At the same time, the simulated GPS can show the position of the ship at real time.
