Integration of Conceptual Design and MOKA into CATIA v5: A Knowledge-based Application for an Aircraft Y-bolt Component

摘要

The design process comprises the Conceptual Phase,the Embodiment Phase and the Detail Design Phase in which commercial PLM/CAD systems mainly support the latter ones.This situation causes the discontinuity in the overall design information flow:Customer Needs (CNs)-Functional Requirements (FRs)-Design Parameters (DPs)-Key Characteristics (KCs)-Geometric Parameters (GPs).There is also a lack of knowledge reuse in routine design process,resulting in large cost-waste of the overall design process.Aiming to enhance the continuity of the design information flow and facilitate the knowledge reuse,this paper makes use of a knowledge-based framework to integrate conceptual design tools:Quality Function Deployment (QFD),Axiomatic Design (AD),Failure Mode and Effects Analysis (FMEA) and the MOKA methodology into CATIA v5 system.A knowledge-based application (KBA) on the large aircraft y-bolt component design is presented as a case study to validate the proposed framework.The result shows how this novel integrated framework and KBA system could benefit designers in a practical way.
