For the die wear in the self-piercing riveting of 5754 aluminium alloy, the finite element model of installed die wear in the self-piercing riveting of 5754 aluminum alloy with two layers of 2 mm thickness was established by Archard theoretical wear model and software Deform-3D. The analysis of the die wear process shows that the wear of installed die is concentrated on the side wall area of middle convex, the maximum wear depth of installed die is 1.28×10-6 mm, the predicted value of die life is 156250 times, the experimental value of die life is 139782 times, and the relative error between simulation value and experimental value is 10.54%. Therefore, the reliability of the finite element simulation was verified. Furthermore, the relationship between process parameters and die wear depth was studied based on the finite element simulation results. The results show that the maximum die wear depth increases with the increasing of riveting speed and die depth and decreases with the increasing of die width gradually.
