Description

Technical field [0001] The invention relates to the technical field of aircraft assembly, in particular to an automatic simulation experiment device for the assembly process and clamping force of the aircraft wing truss. Background technique [0002] Aircraft assembly is the most important part of the aircraft manufacturing process. Because most of the parts of the aircraft wing are large and thin-walled parts, they are prone to deformation during processing, which makes it difficult to control the quality of the assembly. Therefore, we invented a model that can simulate the aircraft wing. The test bench for the assembly process of large thin-walled parts and the clamping force has become an urgent need to reveal its rules. The long truss is a typical variable large-scale thin-walled part in the wing, its length can reach 10 to 20 meters, and the assembly deviation The control is difficult, so the long stringer as the assembly object can better reflect the characteristics of the ...

Problems solved by technology

[0003] At present, in the traditional mechanism, the manual rocker arm is used to apply the loading force on both sides of the clamp, and the clamping force cannot be adjusted in real time. The process needs to be manually adjusted, which wastes a lot of time.
