Simulation of a magneto-mechanical damping machine: analysis, discretization, results

This paper presents and analyzes a method for the simulation of the dynamical behavior of a coupled magnetomechanical system such as a damping 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 Lagrangian finite elements and the sliding mesh mortar method is used to account for the rotation. In time, a one step Euler method is used, implicit for the magnetic and velocity equations. The coupled differential system is solved with an explicit procedure. (C) 2002 Elsevier Science B.V.
