Abstract: To satisfy collaborative design requirements in automobile dies companies, a collaborative design management model was proposed based on the design data and design processes. In this model, design data were organized by using order-project as the basic organizing unit, and projectpart-die tri-layer product structure tree as the organizing form. A segment coding model was set up according to the relationships among design department ,customer and manufacturing department. Each item of code was combined with certain rules to describe data type and data in corresponding department. Process model was constructed to reflect the needs of collaborative development. Design process was defined by attributes such as task object, process mark and process node. Collaborative design task assignment model was set up based on temporal intervals compartmentalization and task precedence. Collaborative design management system was modeled with Unified Modeling Language (UML), and was developed based on a commercial Product Data Management (PDM) system, Aerospace Vehicle Integrated Design & Manufacturing (AVIDM). Validity and feasibility of this system were verified by its implementation in Tianjin Motor Dies Co., Ltd.
