Product Design Change Information Modeling Method Based on Multi Domain Design Information Association Constraints

Product design change information modeling is the basis of realizing intelligent design change. Taking product design change as the starting point, this paper analyzes the information organization form in the process of product design, forms the product design change information model structure of multi domain design information association supporting product scientific design change, expounds the acquisition methods of various design information elements in the model, and studies and designs the construction method of association constraints between various elements of the model. Finally, the design change information model of screw conveyor products and its information management system are established.
