Research And Implementation Of Web-based Interactive Virtual Assembly Key Technologies

With the development of computer network, CAD and virtual reality technology, virtual assembly technology has appeared and developed accordingly. More and more virtual as-sembly technology based-on web are exploited and applied in CAD field. As an important technology to implement network design and manufacture, the application of web-based virtual assembly technology has significant meaning for product design and manufacture in modern manufacturing enterprises and has become the hot research field recently.As a part of the National High Technology Research and Development Program of China (863 Program) "Research on Development and Application of Construction Machine objected ASP" and Jiangsu Province High Technology Research Program, this paper studied web-based visual assembly technology, emphasizing on the architecture of virtual assembly platform and key technologies supporting network virtual interactive assembly, and formed a reasonable solution on the base of existing visual assembly technology in manufacturing. Main contents list as follows:1.EAI communication mechanism of VRML2.Feature based model restructure3.Mapping algorithm of model4.Assembly processing analysis5.Creating mechanism of assembly model6.Optimization of model7.Assembly constraint relations processingPrototype system of Web-based Interactive Virtual Assembly Platform is developed based on studies above, and its functions, such as data management of Network virtual product, definition of assembly tree structure, control of assembly, etc, are implemented and have gotten well engineering application effect.
