Abstract：

For the self-piercing riveting of steel-aluminum dissimilar metals on the reinforcement plate of automobile engine cover, the self-piercing riveting process of dissimilar metals between 6016-T4 aluminium alloy with thickness 1 mm and ST13 steel plate with thickness 1.5 mm was simulated by software DEFORM-2D, and riveting experiments were conducted by flat bottom die and convex die for sheet metal at different placement orders. The results show that the self-piercing riveting quality of steel and aluminium dissimilar metals is better when the flat bottom die is adopted riveted with the upper sheet of 6016-T4 aluminium alloy, and the undercut amount, nail head height and residual thickness are 0.617，0.067 and 0.201 mm respectively. Their relative errors between simulation values and experimental values are 1.65%，4.69% and 2.9% respectively. Therefore, the correctness of the numerical simulation for self-piercing riveting is verified. In addition, the relationship between undercut amount and die parameters of self-piercing riveting for steel and aluminium dissimilar metals was analyzed. The results show that undercut amount increases gradually with the increasing of die width and decreases gradually with the increasing of die depth.
