Abstract: Based on Product Data Management (PDM) system, this paper builds a CE architecture to support product concurrent design. Having analyzed the all design activities, it proposes the digital information model of product whole life cycle and an integration mode between CAx systems based STEP. It defines a IPT matrix organization mode for concurrent design, which supporting the reengineering of IPT. Also, it discusses an information sharing mode and integrates all CAx/DFx tools which are distributed on various operator systems and hardware platforms. Finally, it builds an concurrent product development process model supporting the design micro-circle and prerelease. In addition, it researches the process control and management technology of concurrent product development.

Key words: PDM, concurrent engineering, digital model, STEP, concurrent design
