Study On Data Exchange Of Hull Modeling Data Between TRIBON And CATIA

As the increasingly development of information technology, the computer technology has been applied in various fields in shipbuilding industry. TRIBON system and CATIA system, which are very popular ship design CAD softwares, have been widely used in ship design with their own advantages, therefore, the data exchange between them is necessary intensively. Furthermore, TRIBON system is a peculiar CAD system for shipbuilding with closed character, whose development and application to a deep level have never be solved perfectly. Therefore, this thesis researched the data exchange between TRIBON and CATIA.The data exchange method between TRIBON and CATIA is studied, making hull model the studied object, in this paper. Firstly, the crucial problems on data exchange among CAD systems are analyzed based on the modelling methods of CAD systems.The feasibility, applying conditions and reasons of the adoptable schemes were researched based on the analysis among each scheme in theory and in detail. The data exchange methods were accepted based on data extract interface, modelling interface, objects and features. The feature model of hull was built, as well as the data format of the data storage file was analyzed to express the hull model. Secondly, the modelling methods and the data storage characters of TRIBON system were researched. The data extract method was researched theoretically with keywords, and how to apply this method practically was also investigated deeply. The data resolution methods of the keywords in TRIBON were researched, as well as the data exchange standard based on XML. Thirdly, the system structures of CATIA system as well as the main modelling methods of mechnical parts and products by this system were also researched. Finally, the key issues on the data exchange process were analyzed from TRIBON to CATIA whose feasibility was verified by building prototype system.The data exchange method based on objects and features realized the data exchange, including geometry information and feature information, between TRIBON and CATIA.
