Voronko V. Scientific basics of the automated assembly of aircraft structures under pilot and one-off production

The subject of the study is the aircraft design assembly factory. The purpose of the study is to increase the efficiency and to reduce the production time owing to the application of automated assembly with the use of computer-integrated technologies and robotic systems considering aircraft output volume. Research methods include the process operation analysis and synthesis of the aircraft assembly factory based on computer simulations of the automated assembly of structural elements, the methods of quantum knowledge engineering, the artificial intelligence and expert analysis, the graph theory, the computer modeling of semi-structured problems with the incompleteness of existing knowledge while having a dialogue with a tooling engineer. Experimental studies were carried out with the use of certificated equipment. The following practical results have been obtained. The structures applying the specialized re-adjustable devices with CNC intended to base parts of aircraft structures while being under automated assembly are designed. The algorithm of using artificial intelligence systems for application in the airframe structure automated assembly is developed and implemented. The algorithm of using artificial intelligence systems for application in the process of aircraft automated assembly is also designed and implemented. Software algorithm and structure for the purpose of visualization of aircraft structures automated assembly are proposed. The algorithm allowing the unification of manufacturing processes of automated aircraft assembly with the use of robotic systems up to the limit is described. The novelty of the study is as follows. The concept of automated assembly of aircraft structures using the virtual bases assembly method and applying the specialized re-adjustable devices with computer numerical control (CNC) as well as applying robotic systems was developed for the first time. For the first time the composing method with the use of the virtual bases is proposed and scientifically proved. For the first time a generalized technological approach is created that makes it possible to develop the firmware of assembly processes of aircraft structures. The approach to the world model construction of intelligent assembly robots of aircraft design is improved as well as the organization of assembly processes at the aircraft design assembly factory using robotic systems. The method of calculating the optimization criterion for rational production structure of assembly plants for the conditions of pilot and one-off aircraft production has been further developed. The industrial sector is aircraft building.
