| Abstract: | The 3D finite element model of electromagnetic sheet forming was established and the intensity distribution of magnetic field between coils and sheet was analyzed. After verifying the simulation method with experiment data, the paper analyzed magnetic force distribution on the sheet by loading Current of different direction on double circle and double square coils respectively. The magnetic force and the failure modes of double circle and double square coils were also analyzed. The paper offers structure improvement suggestions and failure prevention methods. According to the characteristics of double circle and double square coils, references are provided for workpieces forming by distributed coils. |
