Abstract:
Electromagnetic riveting is a new kind of riveting technology, which is widely used in aerospace fields. The whole riveting process involves the coupling effect of electromagnetic field and defor-mation field. In this paper, ANSYS finite element analysis software is used to simulate and analyze the electromagnetic field and deformation distributions in electromagnetic riveting. The distribu-tion rules of magnetic field intensity and flux density were obtained. In addition, the distribution of strain and stress was obtained during the rivet deformation.
