AbstractThis paper has two distinct goals. First, we argue in an extended introduction that high velocity forming, as can be implemented through electromagnetic forming, is a technology that should be developed. As a process used in conjunction with traditional stamping, it may offer dramatically improved formability, reduced wrinkling and active control of springback among other advantages. In the body of the paper we describe the important factors that lead to improved formability at high velocity. In particular, high sample velocity can inhibit neck growth. There is a sample size dependence where larger samples have better ductility than those of smaller dimensions. These aspects are at least partially described by the recent model of Freund and Shenoy. In addition to this, boundary conditions imposed by sample launch and die impact can have important effects on formability.

Electromagnetic forming is a kind of processing technology that use lorentz force to make rapid prototyping of metal workpiece, which can significantly improve the metal forming performance,and it is expected to become an emerging technology that alternative to traditional machining to process light alloy materials. Based on the understanding the basic structure of the electromagnetic coupling on the basis of physical process of electromagnetic forming, this article adopt ANSYS sequential coupling method to simulate the electromagnetic coupling process of electromagnetic structure, and analysis of tube electromagnetic forming and plate of workpiece in the process of free bulging deformation behavior. The solenoid coil tubing have an axis of symmetry due to bulging, and it’s electromagnetism load and constraint has symmetry, so its formability is uniform in hoop direction. When the plank free bulge, the distribution of the electromagnetic force caused by the flat spiral coil is not uniform,and the artifacts accelerate fastest in the part of the radius of coil 1/2, but the center area of the workpiece’s forming height is highest.
