Example-based Reasoning for Deformation Design of Typical Aerospace Parts

To address the tedious process of modelling typical aviation parts, it is difficult to achieve rapid modelling phenomenon. Component Application Architecture, or CAA, is used to develop CATIA. It proposes a deformation design method for typical aeronautical parts based on example reasoning. A library of typical part models is first created, then similar models are retrieved by instance retrieval and matching, followed by retrieval of similar models. The next step is to analyze the target design model and the retrieved 3D model, and then make changes to its features to complete the deformation design. The results show that the deformation design method can quickly and accurately create 3D models, improve design efficiency and quality, and provide an effective guarantee for the processing and manufacturing of typical aeronautical parts.
