Research and implementation of model base management system in virtual prototyping engineering of complicated products

To solve the problem of simulation models, normalized management of documents and reuse, a model base management system was developed based on the .NET framework technology in the Collaborative Simulation Platform of Complex Products, with reference on management mode of the PDM enabler specification. The system consisted of users interface layer, business object layer, file/data layer. The business object layer included modules such as basic service, user security management, model structure management and document management. The architecture, function, characteristics and implementation method of the system were discussed in detail. In addition, the system realized the share among other parts of the collaborative platform such as modeling tool, project management and visual environments etc. The .NET remote technology was adopted and the software system had good expansion because it was clearly layered.
