Research on Simulation of Composite Material Assembly Process Based on Key Production Resources

The proportion of high-performance composite materials used in the aerospace industry has increased significantly. In the field of aircraft assembly, although there has been in-depth research on the assembly process simulation of traditional metal winglet parts, there are relatively few research cases on the assembly process simulation of composite winglet parts. In this paper, the production line is first investigated in the trial production stage of a typical composite small wing surface component. Draw a process flow chart, including the preceding process, process time and key resources. Then calculate the logistics path of the entire production line, and get the basic principles of the typical digital factory layout. Then build a 3D model of the digital factory based on CATIA. Finally, a process simulation model is established based on MATLAB to calculate the typical part capacity, resource utilization, resource waiting rate and the waiting rate of each process under different production resource constraints. This model provides decision-making reference for plant equipment layout and capacity analysis of product batch production investment.
