Simulation of a coupled magneto-mechanical system through the sliding-mesh mortar element method
This paper presents and analyses a method for the simulation of the dynamical behaviour of a coupled magneto-mechanical system such as a dumping machine. We consider a two-dimensional model based on the transverse magnetic formulation of the eddy currents problem for the electromagnetic part and on the motion equation of a rotating rigid body for the mechanical part. The magnetic system is discretized in space by means of Langrangian finite elements and the sliding mesh mortar method is used for accounting the rotation. In time, a one-step Euler method is used, implicit for the magnetic and velocity equations and explicit for the rotation angle equation. The coupled differential system is solved with an explicit iterative procedure.
