Research on conceptual design for complex products in grid environment

To resolve problems of collaboration in cross-field design,multidisciplinary model data integration and sharing in complex products simulation and to improve robustness and validity of product conceptual design,a method to build product conceptual design system in distributed environment was proposed by combining grid technology,agent technology,and eXtensil Markup Language(XML) technology.System architecture was established according to the requirements and development process of complex product conceptual design.Communication style,work principle and system workflow were discussed,a unified intelligent agent form for mechanical,electronic,software and control systems involved in product conceptual design was presented and a service-oriented product conceptual design supporting platform was constructed to support distributed,heterogeneous and cross-field collaboration.Finally,further applications of conceptual design technology in virtual reality,virtual prototyping and simulation systems were provided.
