摘要：
The components of the aircraft assembly line and the business logic were analyzed, and a digital twin based modeling framework for the aircraft assembly line was proposed, in order to realize the real-time interaction and deep integration of physical space and information space in the final assembly line of aircraft manufacturers. The modeling and the implementation of the key elements of assembly line were elaborated from the six-dimensional perspective of "human, machine, material, method, environment, and measurement". Correspondingly, the technical process of the three-dimensional visualization and the information integration platform of the aircraft assembly line was proposed. A three-dimensional digital model of the workshop was established in CATIA. Then, a virtual space was built up based on the browser-based framework and WebGL technology and the real-time mapping of physical entities to virtual space was achieved by collecting process data from the shop-floor. An aircraft final assembly line was taken as an example, the synchronous mapping between the assembly workshop and virtual visualization, webServices service and information query service were realized, which improves the assembly efficiency and can provide scientific references for manual decision.
