The effect of tube length in electromagnetic bulging

The electro-parameters and electromagnetic pressure in the process of electromagnetic bulging with mould are simulated using ANSYS, and the effect of with or without mould on the forming of tube blank and the effect of the shape of the mould on the magnetic pressure are analyzed. The results show that, the forming ability increases with the decreasing of the tube blank length. The distribution of magnetic pressure from simulated results agrees well with results from the experiment.
