Abstract


The paper first analyzes the virtual manufacturing , virtual assembly , introduced the current situation of the assembly process of the EMU bogie . The combination of factory assembly process , EMU bogie Virtual Assembly Research and Implementation . Papers on the concept of virtual reality and virtual assembly , characteristics , composition, classification and its key technology to do further research , to discuss the development and application of the status quo of the current virtual assembly technology . On this basis , we propose a virtual assembly system in the EMU bogie assembly , as well as various functional modules realization of the principle and method : a combination of the Visual C 2005, OSG and Qt establish a virtual assembly system of virtual reality environment ; using Pro / E to create a three-dimensional parts assembly solid model ; using Google SketchUp and 3ds Max combination of the the bogie assembly workshop modeling , for virtual assembly system to create a real assembly environment . Finally , system model read . Third, in the virtual environment the user using the mouse and keyboard assembly viewport and product model interact and EMU bogie virtual disassembly . Finally, the air spring bogie example virtual assembly process in virtual assembly environment . By a combination of mouse and keyboard parts disassembly , the system will record the disassembly process and press the user needs for playback , the user can be viewed from all angles assembly process and improve user perceptions of the assembly operations , greatly reduce the cost of the assembly personnel training .
