Research on modeling environment of virtual prototyping based on modelbase and database

Research on modelbase and modeling environment is essential to modeling and simulation technologies. Accompanied with the improvement of simulation, Virtual Prototyping built on CAD/CAM, System Simulation and Virtual Reality technologies is certainly covering all stages of entire lifecycle of the complicated systems. One of key issues on Virtual Prototyping is the technical approach how to build up modeling environment using modelbase, which provides for models reuse, allowing to quickly assembling models running on Virtual Prototyping. With the reference of flight simulation model and the technologies of software engineering, this paper analyses the importance of object-oriented software engineering to modeling, proposes and implements a system hierarchy framework of modeling environment to support flight Dynamic Virtual Prototyping. Following aspects are studied in the paper: model component, different management systems are used to manage model and data, a modeling environment of Dynamic Virtual Prototyping based on graphical modeling interface etc..
