| Popis: | Dual-coil electromagnetic riveting is realized by discharging opposite currents into the coils, and due to electromagnetic induction, a riveting force is instantly generated to deform the rivet. In this paper, a numerical model coupling the electromagnetic field and the deformation field is established using ANSYS software, and the constitutive model of annealed-state 7075 aluminum alloy is derived through the split Hopkinson pressure bar experiment. The result shows that the simulation model is consistent with the experiment. The streamline structure in the rivet head after riveting is reasonable, indicating that the annealed 7075 aluminum alloy can be used as rivet material, and is beneficial to improve the riveting quality. |
