Abstract：

The coil discharge current is the main parameter to influence riveting quality and is determined by different parameters. Effect of different parameters on the coil discharge current was carried out systematically using the electromagnetic field coupling model which was created by finite element method. The results show that different parameters including discharge voltage, discharge capacitance, coil turns, system resistance, gap between the coil and drive plate, drive plate material and drive plate thickness have significant influence to the amplitude and the frequency of coil discharge current. The base of choosing forming parameters and designing technology parameters was established by the coil discharge current analysis in electromagnetic riveting.
