Nonlinear Hysteretic Model of Giant Magnetostrictive Material Baesd on Inverse Magnetostritive Effect
In this paper, a kind of giant magnetostrictive material (GMM) model based on inverse magnetostritive effect was developed. Van de Pol nonlinear difference item was introduced to interpret the hysteresis phenomenon of the strain-magnetic field intensity (MFI) curve of GMM. The coupling relationship between strain and frequency was obtained in partial leastsquare regression method to describe the driftage phenomenon of the strain-MFI curves of GMM in different frequencies. Based on above, the final relationship among strain, MFI and frequency was set up. The result of significance test shows that the effects of all of the items in the final model are remarkable, and that of forecast test shows that the model can describe the characteristics of inverse magnetostritive effect of GMM in different frequencies well. The new GMM model is easy to be analyzed in theory, which is helpful to sensor design.
