Computer Aided Research on Efficient Simulation Prediction and Anti-Deformation Suppression Method for Aviation Panel Riveting Deformation

Aviation panel structure is a typical assembly of aircraft. During the assembly process of metal panel, the inherent forming and connecting characteristics of the riveting process will cause macroscopic deformation such as local subsidence and overall bending moment of the panel, resulting in difficulty in the assembly and coordination of subsequent components. This paper takes the riveting process of the panel with L-shaped stringer applied in an aviation cabin as the research object, the deformation reasons of the L-shaped stringer aviation plate structure are analyzed, and the finite element solid model of the riveting process is established. On this basis, a temperature field equivalent model is proposed, which greatly improves the computational efficiency. Further, a set of anti-deformation active suppression methods for riveted assembly deformation of aeronautical panel structures are proposed for the actual assembly scene, then, the effectiveness of the method is verified by simulation examples and experimental studies.
