Abstract :

Scientists replace the old methods with the new ones as the science develops. Today, automobile makers use thin sheets in order to lessen the weight and forming these sheets needs new methods. Electromagnetic forming is a way with which very thin sheets are made. A magnetic field occurs in the Coils that leads the piece of work to its form like piston but without having effect and forms it when forming with Electronic evacuation. This process happens in less than a micro-second and increases the produced work pieces paying attention to the Coils which are the connection between the work piece and the engine, the amount of Coils in voltage in Electromagnetic forming is studied in digital and experimental ways in this study. For experimental examinations, Electromagnetic Coils are made and tested with Electromagnetic machines with 3 KJ power. In order to do digital experiments Abaqus and J-Mag softwares are used that the digital results have corresponded. The results shown that the area of the Coils should be the same with the work piece and for forming big areas of sheets, forming should be done in several levels with small Coils. Also, in order to increase the strength of Coils during the forming, the should be put in FK20 liquids.
