Nonlinear Characteristic Analysis of Hysteresis Loop for Giant Magnetostrictive Materials

YUAN Hui-qun1,SUN Hua-gang2(1.School of Science,Northeastern University,Shengyang 110004,Liaoning,China;2.Institution of Ordnance Technology of General Equipment Department,Shijiazhuang 050000,Hebei,China)  
Based on the analysis on the inner equivalent magnetic field distribution model of the giant magnetostrictive materials,considering the inner magnetic field characteristic,the nonlinearity hysteresis model was established by introducing eddy current in the time varying magnetic field into Jiles-Atherton model and amending it,and its analytic expression was deduced.The effect of the material on the nonlinearity hysteresis characteristic was discussed by numerical simulation and compared with the experiment in reference .The simulated results indicate that the material inner magnetic hysteresis characteristic is affected by the frequency of the magnetic field,and closely related with the material inner magnetic distribution;considering the material inner magnetic field characteristic,the nonlinearity hysteresis model has a better consistency with the experiment results in reference;when considering material inner magnetic field distribution,the maximum of material magnetic hysteresis curve declines distinctly,and its shape also change.
