In December 2024, the "Digital Twin Precision Assembly Technology for Weak Rigid Large Aerospace Components" was selected as one of the top ten technological advances in China's intelligent manufacturing industry that year, effectively solving the common problems of deformation, low assembly accuracy, and poor efficiency of weak rigid components in large aerospace equipment. Large aerospace components have the characteristics of large size, weak rigidity, and easy deformation. The traditional assembly mode highly relies on highly skilled workers to repeatedly try and assemble, which not only reduces production efficiency, but also makes it difficult to guarantee the stability of assembly quality, and long-term restricts the improvement of aerospace equipment production capacity.
In response to this pain point, the research team has innovatively proposed a closed-loop technology system for digital twin technology. By constructing high-precision digital twin models, virtual perception and real-time prediction of unmeasurable variables in the assembly process can be achieved, while supporting online dynamic optimization of the physical assembly process. In the process of technological research and development, the team focuses on breaking through the coupling of geometric errors and assembly forces, using key core technologies such as assembly accuracy prediction, online planning of optimal assembly paths, and prediction of residual pre tightening force of bolt groups, ultimately forming a digital twin assembly technology system with meter level workpieces, ten micron level accuracy, and hundred millisecond level real-time performance.
The industry's first robotic digital twin assembly system developed based on this technology has been widely applied in aerospace equipment enterprises, completely replacing the traditional manual repeated trial assembly mode and achieving successful one-time assembly of robots. Application data shows that the system can improve the assembly efficiency of large aerospace components by more than 60%, increase the assembly qualification rate from 75% in the traditional mode to 99.9%, and significantly reduce labor costs and scrap rates. Industry evaluations believe that this technological breakthrough not only fills the technological gap in the precision assembly of large weak rigid components in China, but also provides replicable and scalable intelligent manufacturing solutions for high-end manufacturing industries such as aerospace and large-scale equipment manufacturing, helping to continuously improve China's independent and controllable capabilities in high-end equipment manufacturing.
