In the analysis of fatigue life of multiple riveted joints, the explicit dynamic analysis of the pressing and riveting process was carried out, and the deformation form and interference after riveting process were obtained. An APDL subroutine was developed to analyze the riveting process of various forms of specimens. Detailed stress was analyzed by using load-displacement curves of fastener. The load-displacement calculation method of riveted joint was proposed based on the three-dimensional elastoplastic finite element method, and compared with the experimental results, the reliability of using this method to obtain load-displacement curves was validated. Riveting units were established in ANSYS by using parametric modeling to carry out the calculation of riveting load. The fatigue life of the joint is estimated by the stress severity coefficient method. The fatigue test of typical aviation riveted joint was carried out. The calculation results are in good agreement with the test results, which indicates the feasibility of this method.
