Under the background of “dual-carbon” goals and high-quality development

green manufacturing technology is an important direction in recent years. For aircraft products

structural assembly operations account for about half of the workload during the entire aircraft

and it has a direct impact on the final performance

quality and reliability of the products. Improving the greenness degree is crucial for the transformation and upgrading of the production process and the guarantee of product quality. Firstly

green assembly technology was defined as an assembly method system that ensures the geometric accuracy and service performance of the airframe structure. Two core supporting technologies

i.e. assembly processes and quality control

and tooling equipment were proposed

with typical green characteristics such as low consumption

low emissions

high efficiency and high benefits. Secondly

evaluation indicators for structural green assembly technology were constructed. Specifically

it could analyzed from the correlation of assembly efficiency

assembly quality

assembly cost

assembly safety and the greening of tooling equipment. Then combing with specific assembly links

with the perspective of assembly process data driving on virtual pre-verification
