Research on Key Technology of Data Collaboration Supporting Railway Vehicle's Virtual Prototype

Railway vehicle virtual prototype system provides a modeling and simulation environment from product design to product planning and process optimization. Data collaboration is a key technology in this system. In order to support data integration and interaction among distributed and heterogeneous simulation systems in different application domains, and to improve the extensibility and flexibility of the platform, the framework of the layers for the product model data based on their created sequence is proposed. And then the solutions of key problems in each layer are given. In the primary application practice, the platform developed based on above research can effectively support the virtual development for complicated product.
