Abstract: In this paper, a numerical method is proposed for simulating dynamic
response of a ferromagnetic structure immersed in a strong magnetic field
aiming at applications to the in vessel Tokamak structure of RAFM steel. The
magnetic damping coupling effect and the magnetic stiffness coupling effect are
considered in the numerical simulation. For simple, the static magnetic field
is supposed very strong and the material is considered saturated in this work,
i.e., the material is of air permeability but with a strong residual
magnetization. To demonstrate the validity of the numerical method, the dynamic
response of a ferromagnetic plate immersed in a transient transverse magnetic
field with in-plane magnetic field component is simulated with the developed
numerical code and compared with the simulated results with ANSYS. The good
consistency of numerical results and simulation results demonstrated the
validity of the proposed method and the corresponding numerical code.
