Structural and Functional Analysis for Assemblies
This article presents a systemic method for designing assemblies. It is based on generic concepts such as modeling of assemblies using assembly nested graphs which reflect the product design breakdown, the interfaces between components. The proposed method enables to assess the product producibility and the robustness of the assembly process. It eases impact analysis following changes of modified product functions or features.
A software tool, called GAIA, has been developed to support this method; based on a user-friendly interface. It enables specifying assemblies through interfaces and performing a functional and structural analysis of assemblies. Interoperable with the Digital Mock-up and Product Management Systems, it speeds up design changes and impact analysis. Finally, it is useful to grasp the design intents and to capitalize and reuse this design knowledge.
The adoption of this advanced modeling technique in support of the engineering assembly process improves the quality of designed products and reduces the cost of change management, customization and fault rectification by solving assembly issues at the design stage.
