Abstract In the aircraft skin hammer riveting, the deformation of the rivet needs several tens of impacts to realize, and the problem of the initial speed loading cycle of the hammer rivet piston brings difficulties to the analysis process. This paper proposes a software method of automatic analysis of continuous hammer and rivet process by secondary development using the extremely extensibility of Python in ABAQUS. Through the adjustment of input parameters such as initial speed, analysis time and impact times, the hammer and rivet simulation analysis is completed automatically to make the rivet meet the deformation requirements. Compared with the manual single iteration method, the proposed software method and the corresponding simulation program greatly improve the efficiency of hammer riveting simulation analysis under the condition of guaranteeing the heading forming, and bring about the further research on the process parameters optimization and riveting quality evaluation guidance and convenience. Compared with the hammer riveting technology test, the simulation results verify the correctness.
