Abstract：An important source causing vibration and noise of machines with amorphous metal cores (AMCs) is magnetostriction effect of the magnetic material. In order to calculate the vibration due to magnetostriction, an analytical model for AMCs is set up based on piezomagnetic equations. Taking the vibration displacement as variable, the oscillatory differential equations are solved by the variable separation method. This analytical model can be used to predict vibration displacement and vibration acceleration of AMCs. Then the effect of producing processes including stacked and wound, dipped and annealed on vibration in AMCs was examined using measurements of vibration acceleration in AMCs, and related coefficients were also obtained. The outcomes lay a solid foundation for research on vibration and noise of machines with AMCs.
