Axiomatic Design of a Reconfigurable Assembly System for Aircraft Fuselages 2019-01-1359
Modern aerospace industry develops assembly process lines for new aircraft which is produced on a single production line while shortening production times by new technologies. Production processes are developed with systems such as lightweight fixtures, reconfigurable tools, automated part positioning, automated scanning countersink control, automated riveting, robotic measurement etc. These systems provide the necessary flexibility for aircraft fuselage and wing assembly projects. Aerospace manufacturers invest in assembly lines in order to increase production rates and meet growing customer demands. Most of the investments are allocated to state of the art robots for drilling and riveting, sealing, coating and painting applications, in addition to material handling, carbon fiber layup and different types of machining operations.
In this paper, a novel assembly system design methodology is developed by using axiomatic design principles in order to propose a solution to design complexity for aircraft fuselages structures assembly. Frame of design methodology is shaped based on system design methods, academic research and industry requirements. Axiomatic design and reconfigurability principles integrated to methodology for aircraft fuselage assembly. Holistic and hierarchical design approach is demonstrated. It has been shown in the study that the methodology tranforms the reconfigurability requirements into a flexible and scalable system. General assembly system design hierarchy is developed and reasonable alternative is created. Also case study is carried out for Airbus A320 Section 19 fuselage panels in order to demonstrate how methodology is applied. This paper can be used as a reference guide to assembly system design not only for aerospace industry but also whole assembly systems in different industry branch.
