Abstract A magneto-mechanical coupled model for AMWC is established in this paper.By adopting the method of modal experiments conducted on AMWC to amend its elastic modulus, the influence of the wound structure on the vibration of AMWC is studied.Using this proposed model, the magnetic induction, deformation, and vibration of AMWC are calculated by the 3-D finite element method.On the basis of the vibration calculation, the noise field around AMWC is analyzed.An experimental method for measuring the vibration and the noise of AMWC is proposed in this paper.Experimental results confirm the validity of the numerical calculation method.By using the proposed measuring method, the vibration and the noise of AMWCunder different power supply frequenciesand different flux densities are measured.Relationships ofthe flux density versus the vibration and the noise of AMWC caused by magnetostriction effect areobtained, i.e. the vibration accelerationof AMWC isin proportion to the square of the flux density, while the noiseof AMWC are the Logarithmfunctionof the flux density.The curve fittingformulas and related coefficients for the vibration and the noise of AMWC are obtained.
