Research On 3D Concurent And Collaborative Warship Design Based On PDM

Warship design is a extensive collaborative process with many specialities and many systems with long cycle and complex process. Technology design is operated by different systems and construction design is actualized by regions. Different professional designers contrive the same production at the different interfaces of internet in the same design space at the same time. Moreover, there will be continual harmonization between different specialities in the design process . For the moment, the designing means and management model of the internal warship enterprises have much localization. With the development of communication technology and computer technology, effective methods are proposed forward by the concurrent and collaborative design technology.Concurrent and collaborative design is the new design method based on the popularization of computer network, the in-depth research and development of concurrent engineering, concurrent computing technology and collaborative work sustained by computer. It changes traditional design process. Differences among traditional warship design stages became blurry and more users can participate in designs and inchoate examination and approval design. As a result, different stages of traditional design can be operated concurrently which will heighten design quality and reduce time of warship design.As the supporting technique of concurrent and collaborative design, PDM provides powerful automation environment for the concurrent and collaborative design. PDM can firstly support different forms of computer environment including different network and database. Secondly, it can make the management and share of the product data unitive. Thirdly, PDM can expediently encapsulate applying tools, which can availably manage all the information brought by applying tools and provide the platform of information delivery and exchange among application systems. Finally, PDM can provide process management and supervisal and offer the necessary support to the process of concurrent and collaborative design. The work of this dissertation mainly includes:(1) It discusses the primary problems in ship enterprises of our country and puts forward resolving methods.(2) It introduces windchill in detail, which is a software of Production Date Management ,and a futher research of development of windchill.(3) It puts forward the core need of the 3D concurent and collaborative warship design, at the same time accomplishing the 3D concurent and collaborative warship design system based on PDM, aiming at the business operation scene of a certain warship design unit.(4) In Windchill system, the 3D model design flow is custom-tailored and the development work of checking and signing page is successfully completed.
