The Research Of Naval Parallel Collaborative Design Based On PDM

Naval design is a multi-disciplinary, multi-system, large-scale collaborative, long cycle and complex process. The professional designers design the same product in the different interface of computer networks at the same time and the different design space. The design process needs various profession frequent coordination. Becouse of the different storage and processing way, can not transmit information and exchange automatically, so that it is difficult to ensure data integrity, security, and the normal flow of ship products information. With the development of information and computer technology, make the existing ship design tools CAD / CAM / CAE tightly integrated to constitute a demonstration, design, construction, testing, service in one parallel collaborative system, it is a trend of development.Ship parallel collaborative system has changed the traditional design process, makes traditional ship design and research phase to further blurr,users can involve in the design process as well as the early approval design, so that many traditional phases of design work can be carried out in parallel, to maximize the quality of ship design, greatly reduce the ship design time and shipbuilding costs, it can also improve the management level of enterprises and enhance their competitiveness and innovative ability.This paper researches product data management, and explains the basic concepts of product data management, sums up the research at home and abroad, introduces the PDM system and PDM software-Windchill. Focuses on creating team, the management of design document, document approval process, project management, ship design database, and so on. Through the secondary development of Windchill software to achieve and improve the function, build ship parallel collaborative system.
