The aviation product processing line is developing in direction of automation

digitization and intellectualization. The automatic production line puts forward more strict requirements on workshop layout

logistics and production rhythm. The planning and simulation of production line can reflect the possible problems in the process directly and accurately

and solve and optimize these problems through scientific methods. The planning and simulation technology of production line is introduced in this paper. The production process

process layout and logistics scheme of a certain aircraft tube automatic production line are planned

and the running state of the tube production line is simulated using DELMIA/Quest software. Key factors such as the bottlenecks of production line

production capacity and equipment utilization are analyzed

and the improvement plan of production line layout and process route is proposed. The simulation results of different production organization modes are compared

and suggestions on the production line scheduling are given.
