The Digital Integrated Research of Product Design Based on Assembly Model

To improve performance of product in early concept design stage, a digital integrated design and analysis system is proposed which integrated CAD and CAE in the same environment. The system creates a characteristic information center including a set of features parameters and assembly constraints based on analysis of the parameters and assembly relationships of product assembly model. The coherence and reusability of the information expression of product are concentrated on in design stage. The CAD modeling and CAE modeling of product are shared same characteristic information center. So if any of them is changed, the other will be updated in the same time. An example is given to illustrate the benefits of integrated assembly modeling technology.
