A STUDY ON CONSTRUCTING A MACHINE-MAINTENANCE TRAINING SYSTEM BASED ON VIRTUAL REARITY TECHNOLOGY

The development of a VR based training system are presented for teaching disassembling procedures of mechanical machines used in nuclear power plant. The methods of Petri net model for describing trainees' plausible actions in the disassembling process and reduce a right sequence of action sequence are developed as well as realization of the related Petri net editor and the demonstration of the developed VR based training system was demonstrated by example practise of disassembly simulation of check valve. Moreover, the needed future works are also discussed.
