The vibration of electric power device is a serious problem, and is difficult to estimate in its design optimization stage. In this paper, a dynamic magnetostriction model accounting for the dynamic hysteresis behavior is presented by combining the Becker-Doring crystal magnetostriction model and J-A dynamic hysteresis model. The proposed model can correctly describe the physical mechanism of magnetostriction. To compute the vibration of a transformer core, the presented model is incorporated into the finite-element analysis (FEA), and both the Maxwell stress and the magnetostriction are obtained simultaneously. Meanwhile, the vibration of a three-phase transformer prototype is measured to verify the simulation results. It demonstrated that the proposed method was found to adequately predict the vibration of transformer cores.
