Based on Simufact Forming software, the rivet die selection and performance analysis of Self-Piercing Riveting (SPR) joining between DC01 steel sheet and die-cast magnesium alloy AM50A are investigated. The results show that the trapezoidal die exhibits better crack resistance compared with the flat-bottom die and the spherical die. Focusing on the trapezoidal die, the simulation model obtained through iterative optimization accurately predicts the joint forming process and failure modes under cross-peel and tensile-shear loading conditions. Furthermore, the simulated load-displacement curves, peak load and absorbed energy are highly consistent with the experimental results. The "process simulation-performance prediction-experimental validation" research framework established in this study can effectively support the rivet die selection and optimization for steel-to-magnesium SPR process, where the simulation method holds core value in crack resistance analysis, failure mode study and joint performance prediction.
