Research on Modelbase System of Dynamic Virtual Prototyping Based on Component Technology

One of key issues on Dynamic Virtual Prototyping is the technical approach of how to build up modelbase system which highlights model reuse, modelbase management system, and modeling environment. Alerting to the requirement of the characteristics of Dynamic Virtual Prototyping, this paper analyses the importance of introducing component technology into modeling, designs model component to improve model reuse, and offers a hierarchy framework and corresponding methods of modelbase management. In addition, a graphic modeling environment based on modelbase is applied to study on Dynamic Virtual Prototyping.
