Abtract: Finite
element method for numerical simulation of electromagnetic field is
stated . At first, mathematic model for electromagnetic used in 630 kN
multipoint forming machine is constructed and its magnetic force is
solved with Maxwell stress tensor method. A big improvements on magnetic
are made. Distribution curve of vector equipotentiol of electromagnetic
field and electromagnetic traction are obtained, ratio between the
biggest electromagnetic traction and working traction is 2.27-magnetics
of quasi-constant force.
Key words: Electromagnetic Finite element method Mathematic model
