Abstract：

In order to analyze the change law of electromagnetic field on electromagnetic riveting process,numerical simulation method was used to establish the electromagnetic field coupling model which was a voltage source by ANSYS.Through measuring the discharge current of the coil with diverter,the coupling model was proved to be doable.The simulation results show that the drive plate is mainly subjected to axial magnetic force,whose distribution is non-uniform along the radial direction of the drive plate,and the maximum value of axial magnetic force locates in about half of the drive plate radius.At the same time,the magnetic force along the driver plate thickness is a gradient distribution.Between the coil and drive plate,the magnetic field is mainly radial and the infiltration magnetic field is an attenuation distribution.
