Construction method of intelligent assembly system based on digital twinning

Abstract

The invention discloses a construction method of an intelligent assembly system based on digital twinning, and belongs to the technical field of intelligent manufacturing, and the method comprises the steps: carrying out the real-time collection of the dynamic data of an assembly process of a physical workshop through a data collection system according to the dynamic data elements of the technical physical workshop of a complex equipment product assembly production site; pre-processing and standardizing, and storing into a database; a digital twin workshop model is used as a system client, and through interaction with a database, unified data service drives an assembly part three-dimensional virtual model and a product three-dimensional model, so that bidirectional dynamic mapping between a digital twin workshop and an assembly production physical workshop is realized; based on three-dimensional visualization system integration, construction of an intelligent workshop digital twinning system is completed, so that the functions of real-time state display, state evolution, data input, data storage and the like in the digital aircraft assembly process are achieved, and the problems that existing digital workshop data are monotonous in presentation and poor in interaction and immersion are solved.
