The traditional process based overall design of civil aircraft equipment racks requires designers to use structural and system digital prototypes to repeatedly coordinate and iterate to form equipment rack layout schemes, which heavily relies on the designer's engineering experience, the iteration speed of the plan is slow, and the evaluation of the advantages and disadvantages of the schemes are difficult to quantify, which have significant impact on the aircraft development cycle and overall economy. This article conducts research on ant colony algorithm state transition rules, search path optimization, pheromone updates, etc., and completes the design of intelligent location planning algorithm for equipment racks. Based on the advantages of react componentization, visual development of intelligent equipment rack layout is completed. Finally, the intelligent algorithm of the equipment racks and the Web UI are combined to complete the research and design of the V1 version of the intelligent layout system for civil aircraft equipment racks. The designer can run the algorithm with one click on the operation page, and the equipment racks layout scheme calculation is automatically displayed on the Web page, the calculation results can also be imported into CATIA for digital prototype design according to design needs.
