Study And Develop On Virtual Reality Simulation System Of The Ship Controllable Propeller Pitch

With the rapid development of shipbuilding industry and automatic control technology, the CPP (controllable pitch propeller) propulsion plant has gained widely application in ships. STCW Pact has listed the propulsion equipment of CPP ships as an essential training item for senior engineer.Cultivating high quality, high skills senior engineer by theory teaching is not enough; we should still strengthen the practice operation ability. So, many senior engineer training institutions apply Training Ship Simulator. But the traditional simulators are physical simulators and2-dimension software simulator that developed by the C#or C++software. The former simulator acquires good visual effect, but it has the disadvantages of limited expansion and high cost. Although the later simulator can make up the former’s deficiency, it still has the disadvantages of not realistic enough; the trainees can’t have a vivid image of the actual equipments. Based on the advantages and disadvantages of the two former simulators, the main content of this paper is to develop a ship CPP VR simulation system that contains2-dimention control system and3-dimention virtual scene by applying the VR (Visual Reality) into the simulators.Firstly, this paper analysis the CPP Propulsion Plant’s structure, CPP’s operation properties, advantages and disadvantages of the ships equipped CPP Propulsion Plant and CPP’s structures and operation principle. According to the list properties and the basic equations of ship propulsion system, this paper divided the system into three parts:propellers, CPP’s pitch control structures and the ship-diesel engine-propeller system. Modeling and simulating the three parts.Secondly, this paper made and refined3d visualization models of Ship, CPP Propulsion Plant and hydraulic control system refer to the equipment of the actual CPP Propulsion Plant.Lastly, by the mathematical model and the control system’s requires, this paper developed a system contains CPP Propulsion system and3-dimention virtual scene with the help of Microsoft3-d games development platform Microsoft XNA Game studio. This system includes bridge control panel, engine room control panel, local control panel, CPP hydraulic control system and3-dimention visual scene.This paper shows that applying Microsoft XNA Game studio3-d games development platform into the Training Ship Simulator is feasible. At the same time, it has the following advantages:flexible development methods flexible, good expansion ability, and higher program efficiency. The system has taken the second prize in11th national challenge cup.
