Abstract: The approximate uniform magnetic field force can be generated by uniform press coil, and the differences of uniform distribution of magnetic field force by different coil structures are significant. In order to study the effect law of coil structure parameters to uniform distribution of magnetic force in electromagnetic sheet forming, the 3D finite element models for electromagnetic field analysis were established by software ANSYS. The structure parameters on the distribution uniformity of the magnetic pressure were analyzed. The method of improving the electromagnetic forming force distribution uniformity of uniform press coil was proposed, which will improve the effect of electromagnetic forming and expand the scope of the application.
