Abstract: The heterogeneity of product structure information makes it difficult to implement the virtual prototype engineering of complex product and causes inconveniency in collaborative manufacture network environment. To solve this problem, under background of one project for national 863/CIMS subject, a new approach was brought forward that adopted Web Service Technology, Software Integration Technology, XML Serialization Technology and Product Data Management (PDM) Technology, as well as an object-oriented product structure information model. And whats more, by means of Data Interchange Format, one implementation scheme and an information integration framework for product structure information were also put forward to solve the problem existing in the virtual prototype engineering of complex product. As a result, information heterogeneity caused by the use of different CAD application systems was eliminated, and product structure information of virtual prototype was integrated effectively for collaborative product manufacturing in network. All of this has been proved for its validity in practical engineering.
