Research on Technology and Methodology Architecture of Virtual Prototyping Technology

Virtual prototyping technology (VPT) is a digital design methodology and means newly-developed based on some existing technology, such as modeling/simulation, CAx/DFx, virtual reality, etc. An architecture of the technology and methodology involved in VPT was proposed, which was composed of virtual prototype, simulation based on virtual prototype, management of virtual prototype, the integrated technology of all kinds of tools, and the human-machine interface. Then, each individual technology was further discussed, including the definition, characteristics and modeling method of virtual prototype, the classification, method and feature of multi-discipline simulation, the management method of virtual prototype, and the integrated technology of all kinds of application tools.
