| Electromagnetic riveting is a new kind of technology that is based on electromagnetic forming and traditional riveting technologies. In this paper, the analytic model of process of electromagnetic riveting has been established, and the process of riveting has been simulated by ANSYS software. The correctness of analysis results has been proved by corresponding experiments in the end.The circuit and electromagnetic field is connected by one node, and the circuit and electromagnetic field model is built by direct coupling. From the model, we can solve and gain the values and change orders of charging current, charging voltage, discharging current, discharging voltage and inductive current. After that, the electromagnetic fields can be created from two circuits' currents, and their magnetic rector and flux can be simulated from ANSYS solver. The simulation results indicate that the two circuits' currents have the same frequency and the inductive current is at the same quantity class as the discharging current.The plastic kinetic response of rivet is analyzed by sequentially coupling which take the first step's result as initial conditions. The process of forming and changing of plastic elements is simulated by ANSYS/LS-DYNA solver, and also computes the distributing of element stresses and element strains. The postprocessor analyze the distributing characteristic and the changing orders of stresses and strains, as well as maximal stress fields and maximal strain fields.ANSYS simulation results indicate that both the maximal stress and maximal strain locate nearby the central forming field but they are not superposition. The forming extent of the central forming field is very large. From ANSYS solver, aluminum alloy rivet's minimal ratio is 5 to Finally, we have made some experiments by using aluminum alloy and stainless steel rivets. The result of experiments is very like the simulation. This powerfully proves the correctness of the digit simulation result of electromagnetic riveting.
