To ensure the riveting quality and avoid riveting defects such as overdriven head or underdriven head, elastic and plastic mechanical analysis of the riveting process has been studied and a riveting energy control method is proposed in this paper. According to the target size of the driven head, the material properties, and the interference, the total riveting energy is calculated. Then, the relation of riveting duration and riveting energy is established to realize the control of the riveting impact energy in practical engineering. Furthermore, plastic dynamic impact buckling of the rivet is also analyzed to get impact buckling critical speed. Due to the dual-robot posture adjustment and countersunk self-centering ability, the working axes of the riveting tools, rivet, and hole are found to be well coaxial. The analysis shows there is little phenomenon of rivet bending in the dual-robot pneumatic riveting system and the impact buckling critical speed is much higher than the piston impact speed. Finally, finite element model is built for riveting dynamic simulation and dual-robot pneumatic riveting cell for fuselage panel assembly is developed to obtain experimental results. The comparison shows the proposed method has a good performance. The research results enhance the knowledge of energy effect of dual-robot pneumatic riveting, and thus offer positive guidance for practical application in aircraft assembly.

“…6, the compressive stress through the sheet thickness is significantly uniformless due to the expansion of the rivet and the resulting interference of the upsetting side is 1 % greater than the other side. According to [27,34,35] the average of the sufficient interference of the riveted hole is 2 to 3.5 % and varies between 1.5 and 4 %. So, the uniformless expansion of the wall of the hole becomes the main factor of the deformation of the workpieces.…”

This investigation is performed to develop a methodology for the variation analysis and prediction of aircraft fuselage panel riveting assembly. Firstly, according to the manufacturing process of the part of the aircraft fuselage panel, the method of influence coefficient (MIC) based on key feature deviation is proposed. Secondly, the mechanism of component deformation in riveting process is expounded, and the method to approximately compute the global distortion, caused by rivet deformation, of the fuselage panel is presented. The proposed method is illustrated through a case study on the riveting assembly process of a sidewall panel, the local plastic deformation near the riveting holes is ignored but the computing resources are saved, the complex and timeconsuming computation are avoided. The reasonableness of the proposed method is verified by the measurement data of the prototypes.

Multiple site damage (MSD) in aircraft structures can be defined by the presence of numerous minute cracks arising at different locations such as rivet holes in lap joints. One source of initiation can be due to residual stresses induced in the lap joints during the riveting process. This paper describes a finite element methodology of a quasistatic, displacement controlled riveting process to capture the local geometry features representative of service hole quality for accurate simulation of residual stresses in riveted lap joints. A three-dimensional finite element (FE) model that takes into account material, geometric, and contact non-linearities is developed using ABAQUS/Standard 6.4-1 to simulate the joining process. The interest of FE simulations is to conduct parametric studies to observe effects of varying hole clearance, misaligned holes, friction, and presence of debris on the residual stress state in the skin. Based on studies conducted, comments are made regarding any observed variation in tensile hoop stress, which is the primary source of fatigue cracks in riveted lap joints. A relation between the rivet-head deformation ratio and rivet-head height with applied displacement is developed using the finite element model, as a means of controlling the rivet-head deformation.
