Electromagnetic tube calibration is a kind of advanced working techniques.During the process,the tube is forced to impact and fit to the inner contour of the die at very high speed by magnetic pulse force.At present,the electromagnetic forming technology is mainly applied in tube bulging,tube compression and flat forming.And research on the correlative theory and technology of electromagnetic tube calibration is insufficient. A strong coupled electromagnetic-structural model based on ANSYS restart analysis is proposed in this paper.In the model,the influence of the tube deformation on the magnetic field is considered,so that the electromagnetic forming process can be simulated accurately and the effect of the air mesh distortion on the tube deformation is avoided effectively.The electromagnetic force magnitude and distribution with different deformation in electromagnetic bulging with die are analyzed and the moment of maximal electromagnetic force is researched.In addition,the distribution of eddy current and electromagnetic force is presented.
