Intelligent Design of the Digital Twin Assembly Process for Complex Products

In view of the complex technology status, the complex assembly process and route, being prone to assembly errors, low assembly quality and accuracy, low assembly efficiency, long assembly debugging cycle, we conducted research on intelligent design of assembly process based on digital twin, proposed intelligent design method of assembly process based on digital twin, provided real time intelligent analysis of assembly quality based on digital twin, and assembly process dynamic intelligent optimization design. We verified it by taking the assembly of aircraft wing box as an example. We conducted real time intelligent analysis of assembly quality based on twin data, conducted the intelligent optimization design of process scheme through twin data. The assembly site is controlled by the feedback. The process and assembly are optimized with virtual control. The assembly repetition is reduced, the assembly efficiency is improved, and the assembly quality for the products is enhanced.
