Abstract

Abstract: In the assembly of aircraft composite components, molding errors are often eliminated through rigid constraint methods such as pallets. The constraint profile of the pallets is consistent with the theoretical shape of the component. Since composite materials have uncontrollable molding errors, this rigid constraint the control method may cause composite material damage. This paper obtains the physical shape data of composite material components through digital measurement, reconstructs its shape model, and designs a flexible multi-point force-applying head to control the shape of the component. A solution scheme that combines finite element calculations with genetic algorithms is proposed. The goal is to ensure that the actual shape of the composite material components matches the theoretical shape as closely as possible without causing damage. This method is verified through an example of a certain type of aircraft radome composite material cover. The shape of the cover is constrained according to the original plan of using a constraint card plate. The accuracy between the actual shape and the theoretical shape at a given position is only 66.7%. Through this method, a multi-point pressure head is used to control the shape of the cover. The accuracy between the actual shape and the theoretical shape at a given position reaches 91.7%, which is 25% higher than the original plan.
