Research On Virtual Reality Technology Of Main Engine On MV "YUKUN"

China is a large country of ocean transportation. Because the overall competence and work ability of the crew take important affect on the situation and safety of the shipping industry, that how to improve the quality of the crew through training is the significant responsibility and mission of the high maritime colleges and other related training institutions. The working process and disassembly of the main engine is one of the most important training programs. Because the quantity of the experimental installation is limited, and the equipments are expensive, the training of the disassembly of main engine is uneconomical. However, combing the virtual reality technology with the actual disassembly to train the crew is not only economical but also efficient for the training.Based on the analysis of the structure of the main engine, the working process of one cylinder, the working process of the crank-connecting rod mechanism, the working process of the propeller and the property of ship in coordination with main engine and propeller, it takes the main engine on MV "YUKUN" for an example to collect the related data. And it screens the data, establishes the 3D model by SolidWorks and optimizes the model by 3D MAX according the data. Then it imports the 3D model into the EON Studio to achieve the roam of main engine. It combines the C#.NET with the EON Studio to realize the HCI (human-computer interaction) and then makes the virtual disassembling, starting, stopping and speeding up and down come true. In addition to that, it shows the temperature variation curve of the working process of one cylinder in the virtual-reality environment to realize the multiple training by virtual reality technology. The virtual reality system for the main engine can achieve almost all training programs in the actual laboratory or engine room, and this system can be installed illimitably and economical.This main engine virtual reality system can be in good cooperation with the going marine simulator and it will surely be meaningful to the research and development of a late-model marine simulator.
