摘要:Considering the steel plate bending by induction heating, a numerical model for the coupling analysis of electromagnetic-thermal-structure used in moveable induction heating process of the steel plate was built based on ANSYS Multi-physics.For simulating the moveable heating process in practice, the model used the "node con-straint equation technology"to solve the multi-field coupling in the solution domain, which is comprised of steel plate, inductor, and air gap.Numerical calculation results were in alignment with experimental data, which verified the validity of the numerical model.In this paper, numerical analysis was conducted for the induction heating process.The main conclusions are as follows: eddy current concentrates on the plate area in front of inductor, which is beneficial to rapid heating of the plate and rapidly entering into the quasi-steady heating status.At the end of induction heating, the expansion of magnetic flux density forms the unique end effect of induction heating, thus affecting the temperature distribution and final deformation of the plate edge.
