| Abstract: | A mathematical model was deduced to describe the finite element method(FEM) simulation of induction heating with the magnetic vector potential with the ANSYS software.The coupled thermal and electro magnetic field problem taking account of nonlinear materials characteristics related to temperature was discussed.The induction heating process of cylinder workpiece was analyzed,and the temperature distribution and its variation with time were obtained.The results show that the simulation results are in accordance with the practical application. |
