数字孪生驱动的航空发动机装配技术

In order to implement the interaction and fusion between virtual models and physical states, a digital twin-driven aero-engine assembly technology was investigated herein. The composition, structure, function and procedure were addressed. Key enabling technologies, including assembly procedure control, part selection and matching, assembly operation guide, assembly clearance control, configuration control, and correlation analysis of assembly data and test driving data were studied in detail. The work was believed to improve intelligence, activeness, predictability of assembly procedure control and configuration control and also to support decision-making and optimization based on physical states. The assembly efficiency, normalization, successful assembly ratio, and quality consistency may be improved. The work provides a theoretical and technical reference for research and development of digital twin-driven aero-engine assembly technology.
