Research on Assemblability Evaluation Method of Aero-engine Based on Assembly Data Model

Abstract

In order to improve the assemblability of aero-engine products, this paper combined with the assembly process design features of the engine, and divided the assemblability into five directions, assembly performance, assembly structure, assembly connection, equipment capability and other requirements. The engine assembly data model was used as the carrier of product assembly process information integration; the fuzzy set and expert system were introduced to organically combine the product assembly process and the assembly parameters. Evaluation levels in all aspects of the engine structure assemblability are determined by the analysis and evaluation of a single factor and comprehensive impact. High-level assemblability analysis was achieved by means of that. The algorithm proposed in the paper had been applied to engine assembly process design practice and had achieved good practical results.
