Prediction of geometrical variations in Airbus wingbox assembly

Purpose - This paper aims to present a method for predicting dimensional variation in assembly processes of a wingbox structure concentrating on the assembly of skin panels to rib feet. Design/methodology/approach - Finite element modelling and experimental tests are conducted on the rib structure based on the site measurement gathered from the Airbus assembly factory. Findings - The results have shown that the simulated model has the capability of predicting to an acceptable degree of accuracy the overall geometrical variations of the ribs and skin panels, as well as the positional variations of each individual rib foot. Originality/value - The authors believe that no previous research has offered a similar prediction method for large aerostructures.
