Abstract: According to status of the low conventional assembling efficiency and high cost of the mine scraper conveyor,taking a mode scraper conveyor as a study object,the Pro 1 Engineer was applied to the basic modeling. With integrated double channel prop scene system as the hardware support,with the Visual Studio and Ope n Scene Graph as the software platform of the system,a virtual assembling system of the scraper conveyor with a virtual hand model operation,automatic display,ollisio n inspection,route recording,coordinated assembling and stereo display and other functions were realized. The system with good immersion and interaction could impro ve the assemblability of products and the development efficiency of scraper conveyor and could reduce the design cost.
