英文摘要:

      The purpose is to satisfy the users' cognition of the structure and function of the offset presses, provide a virtual structure display platform for the product operation manual, and facilitate the users to quickly understand the relevant information of the offset presses. Pz1740e sheet fed offset press is selected as the real machine model to build a three-dimensional model. The offset press model in. FBX format is imported into unity to build the scene environment, develop the interactive function, compile the disassembly and assembly script code, and realize the production, development and optimization of the system software. The operation manual displays the multi-dimensional information of graphic content. Users can use the system to control the automatic assembly process, display the structure and information of hidden parts, and observe the internal and external structure of the offset presses in an all-round way. According to the structure related information content, users can click the specific component structure to display its name, function, possible faults and printing faults. For the faults, Users can adjust the control bar to observe the change of the dirt marks on the back. Three dimensional modeling technology is used to realize the virtual display function of offset presses, and virtual reality technology is used to realize the human-computer interactive function; the structure display and function information introduction of offset presses are supplemented with the three-dimensional display of graphic content to provide the printing theoretical knowledge foundation and structure display learning foundation for the following offset presses virtual simulation system and fault simulation system.
