摘要：

This paper considers the dynamics of an electromechanical system consisting of a ferromagnetic mass fixed on a spring and subjected to an AC electromagnet. Subharmonic and bursting oscillations are found and their shape analyzed when one varies the viscous damping coefficient, the number of turns of the coil, the frequency and amplitude of the AC voltage. Pulse packages patterns and sharp burstings are observed in the motion of the mechanical part. (C) 2011 Elsevier B.V. All rights reserved.
