摘要：

Current frequency is one of the most important parameters that must be analyzed and optimized for the analysis and design of electromagnetic forming process, and its effects on the electromagnetic forming process are very complicated. The influence of frequency on electromagnetic tube compression has been investigated by means of the sequential coupling numerical simulation. The delaying and the total time of the forming process prolong with the lowering of the frequency, and the optimum frequency is found that corresponds to the largest deformation and the greatest plastic strain energy of the tube. There is a special range around the optimum frequency, where the corresponding deformations are similar and the relative skin depth is between 0.61 and 0.70. The maximum energy efficiency of the electromagnetic tube compression is 13.76% in this work, which is corresponding to the optimum frequency. (C) 2008 Elsevier B.V. All rights reserved.
