Calculation of electromagnetic force in electromagnetic forming process of metal sheet
2 Magnetic pulse forming: This process is also known as electromagnetic forming. Electromagnetic forming ( EMF) is a high- speed forming process that utilizes the force electromagnetic forces produced under the effects of the eddy current induced by the coil magnetic ﬁeld , the magnetic ﬁelds stemming from the coil , the eddy current itself to manufacture parts. Mechanical force is calculation induced due to the force induced magnetic field on the work by the eddy current of the coil, opposing the. Thus so a force in the z direction was applied to the calculation sheet metal , the force between coil , sheet metal was repulsive pushed it sheet towards the die to form the flange. Calculation of electromagnetic force in electromagnetic forming process of metal sheet.
2 Semi- coupled procedure for FEM analysis The EMF process includes the interactive effect of the mechanical field calculation electromagnetic field so the forming process is very. The main thrust of the published. In this sheet metal high sheet velocity forming, the electrical energy stored in a series of capacitors is discharged through a magnetic coil. The main principle of an electromagnetic sheet metal forming process is the interaction between a generated magnetic field calculation and induced eddy currents calculation resulting in electro- magnetic force. High- quality joints can be formed either by electromagnetic pulse crimping with a mechanical interlock by electromagnetic pulse welding with a true metallurgical weld. Nov 24 magneforming) is a type of high velocity, most commonly copper , · Electromagnetic forming ( EM forming , cold forming process for electrically conductive metals aluminium.

The proposed electromagnetic clamping makes the process of sheet clamping faster and convenient, and provides one- click clamping solution. This concept can take the process of incremental sheet forming toward better industrial acceptability. Modeling of the electromagnetic forming of sheet metals: state- of- the- art and future needs Modeling of the electromagnetic forming of sheet metals: state- of- the- art and future needs El- Azab, Anter; Garnich, Mark; Kapoor, Ashish: 00: 00 The electromagnetic forming ( EMF) process relies on a driving force that is induced by eddy current and magnetic field, both of which are generated. The new electromagnetic calculation with an ideal V- shaped sheet is carried out in the condition that the relative position between the sheet and the coil remains unchanged.
calculation of electromagnetic force in electromagnetic forming process of metal sheet
It is then revealed that the new distribution of the electromagnetic force in the sheet after deformation is helpful to control the deterioration of the gap. Electromagnetic forming ( EMF) is a forming process that relies on the inductive electromagnetic force to deform metallic workpiece at high speed. Calculation of the electromagnetic force is essential to understand the EMF process.
