Outline
This study focuses on the adhesive-rivet composite connection of automotive body dissimilar metal sheets. A finite element model of adhesive riveting and self-piercing riveting composite connection established using Simufact Forming software. The upper plate made of 1mm DC04 steel plate, and the lower plate made of 2 mm 5052 aluminum alloy plate. The adhesive-rivet composite connection process using epoxy resin structural adhesive simulated using finite element analysis. By analyzing the specific parameters of the internal locking value, nail head height, and remaining thickness of the adhesive-rivet composite joint by changing the height of the rivet, the depth of the concave mold, the height of the convex platform, and the pressing speed, it found that the optimal forming process achieved when the rivet height 5 mm, the diameter of the concave mold 10 mm, the depth of the concave mold 1.9 mm, the height of the convex platform 0.9 mm, and the pressing speed 45 mm/s. And the simulation results are verified through riveting equipment, and the trend of riveting force change in both results the same as the shear tensile failure mode. The error of joint characterization parameters within 10%, which further verified the high reliability of Simufact Forming software.
