The interconnection between the physical world and the information world in the aircraft assembly workshop has become the trend of aircraft assembly intellectualization. Digital twin is an effective technology to achieve interaction and integration between the physical world and the information world. This paper analyzes the development of the aircraft assembly shop-floor and expounds the characteristics and problems of the aircraft assembly shop-floor. On this basis

the framework of digital twin shop-floor for aircraft assembly

which covers the physical assembly shop-floor

the virtual assembly shop-floor

the twin data of the shop-floor and the assembly shop service system

is proposed. The key technologies such as real-time perception and acquisition of the physical assembly shop-floor data

modeling and simulation technology of virtual assembly shop-floor

digital twin and data-driven of the assembly production management and control are illustrated in detail. This study will provide reference for intelligent manufacturing in aviation industry.
