Abstract：Riveting process parameters have an important effect on interference in self-sealing riveting. Based on
DEFORM-3D software, 4mm round head self-sealing rivets made of 2117-T4, and panels of 2024-T3 are discussed to analyze
the effect of three main process parameters, which are hole-diameter, iron shape and pressing force on riveting quality.
The simulation results show the riveting interference can be increased within 4.01-4.02mm hole-diameter, by using groove
iron and high-pressing force. Therefore, the sealing performance can be improved.
