STUDY ON THE TRACTION CHARACTERISTIC OF ELECTROMAGNETICS OF QUSI-CONSTANT TRACTION

Abstract

Abstract: 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, Electromagnetic field, Finite element method, Mathematic model
