For the riveting of aluminum alloy sheet in battery box of electric vehicle, the finite element model of self-piercing riveting for sheet metal was established, and the process of self-piercing riveting for 5052-H32 aluminum alloy sheet with thickness 1.5 mm was simulated by software Deform-2D. Then, the simulation results were verified by riveting equipment and installation die, and the relative errors between simulation values and experimental values of interlocking length, residual thickness and head penetration were 11.46%, 5.37% and 2.86% respectively. Therefore, the correctness of finite element simulation was verified, and the influences of process parameters on the riveting quality of sheet metal were analyzed based on finite element simulation. The results show that the interlocking length increases with the increasing of die convex height and riveting speed, while it decreases with the increasing of die depth. However, the head penetration and residual thickness decrease with the increasing of die convex height and riveting speed, while they increases with the increasing of die depth.
