| Vessel virtual design is a whole-digital product development technique, which aims at vessel products on base of virtual reality. It can not only improve the efficiency of vessel design and resolve the boring iterative modification, but also help users to design, analyses and manufacture products by virtual product model, modify the design-period incorrectness in time and meliorate the quality of vessel design, adopting virtual design technique to build life-cycle-faced product model in accomplishment of vessel structure design. It can also save costs in building products in physical, shortcut the spending in manufacture, reduce the cycle of vessel manufacture, ensure the success in product development and enforce enterprise the ability of response agility in high-changed market in the meanwhile.Solidworks is a CAD/CAE/CAM/PDM desktop system in windows. It has been widely used in mechanical manufacture as a successful virtual design system. It can be developed by any languages that depends OLE and COM techniques such as VB, VC, Delphi. With Solidworks API function, users can easily develop the applicable virtual design system according to product's characteristics in different fields.The paper brings forword a vessel structure virtual design systems, which secondly developed with object-oriented programming in Solidworks. It mainly introduces the structure of the system and the functions of main modules, discusses the key techniques and methods in modeling data product in virtual design. On the basis of results from lines design, system can establish a 3D vessel hull model and complete vessel structure design. The system realizes the main functions in virtual design system, including parametric modeling, dynamic modifying and data product managing. A uniform vessel product data model that integrates designing and manufacturing information can be built in computer, which can help users obtain graphic and digital records in product, and use them in the following design and manufacture. |
