The virtual assembly is an advanced manufacturing technology that develops in recent years. This technology can carry out the pre assembly on the 3D model of diesel engine or components using virtual reality technology in a virtual environment. And it can improve the product design and structure of assembly by analyzing, evaluating, planning and simulating, under the conditions of meeting the product performance and function, by this can improve the product assembled character and economy. This article mainly introduces the research state of virtual assembly,overall structure of the diesel engine virtual assembly system and the key technology of the diesel engine virtual assembly. The key technologies include virtual as sembly modeling technology,virtual assembly simulating technology,virtual assembly controlling technology and virtual assembly supporting technology and so on.
