Development of a virtual simulation system on CRH3 EMU bogies for maintenance

This paper developed a virtual simulation system on CRH3 EMU bogies for maintenance, integrating with virtual simulation technology, computer simulation technology, modeling technology, virtual reality technology and multi-media technology, where the structure characteristics of CRH3 EMU bogies and requirements for maintenance are considered. The key technologies applied in the developed system were introduced in detail including 3D modeling and model converting for CRH3 EMU based on modularity, 3D visualization based on virtual reality, dynamic assembly simulation, information searching and inquiring and multi-media implementation. The system proposed in this paper can contribute to engineers to make reasonable and cost-effective maintenance plans, and can also be used to train the maintainers. In accordance with the structure characteristics of CRH3 EMU bogies and requirements of maintenance, virtual simulation technologies, computer simulation technology, modeling technology, virtual reality technology and multimedia technology are integrated to develop a virtual simulation system on CRH3 EMU bogies for maintenance. Key technologies applied in the system development include 3D modeling and model converting for CRH3 EMU based on Modular structure, 3D visual viewing based virtual reality, dynamic assembly simulating, information searching and inquiring and multi-media implementing.
