摘　　要：该文引入小磁滞回线下磁能损耗数学模型,使用AMH-1M-S型动态磁特性测试系统测量了Fe-Co-V、Terfenol-D与Fe-Ga合金样品的高频磁滞回线,利用实验测试结果结合数学模型对比分析了三种材料的磁导率幅值、介质损耗因数、介质储能和电磁损耗变化规律。当励磁磁场频率为50kHz时,随着磁感应强度的增加,Terfenol-D和Fe-Ga合金的介质损耗因数近似线性增加,三种合金样品的电磁损耗均增大。当磁感应强度为0.03T时,随着励磁磁场频率的增加,Fe-Co-V、Fe-Ga合金磁导率幅值都先增大后减小,Terfenol-D合金的介质储能增加最快并且其电磁损耗随频率增速最快。在1~40kHz内Fe-Ga合金的电磁损耗高于Fe-Co-V合金,在40~60kHz内Fe-Ga合金电磁损耗低于Fe-Co-V合金。该文结果为磁致伸缩材料的电磁损耗分析与高频器件设计提供了依据。In this paper, the mathematical model of magnetic energy loss under small hysteresis loop is introduced. The high frequency hysteresis loops of Fe-Co-V, Terfenol-D and Fe-Ga alloy samples are measured by AMH-1 M-S dynamic magnetic characteristic testing system. The experimental results and mathematical model were are used to compare and analyze the magnetic permeability amplitude, dielectric loss factor, dielectric energy storage and electromagnetic loss of the three materials. When the excitation magnetic field frequency is 50 kHz, the dielectric loss factors of Terfenol-D and Fe-Ga alloys increases linearly with the increase of magnetic induction intensity, and the electromagnetic losses of all three alloys increases. When the magnetic induction intensity is 0.03 T, the permeability amplitudes of Fe-Co-V and Fe-Ga alloys increases first and then decreases with the increase of the frequency of the excitation magnetic field. The dielectric energy storage of Terfenol-D alloys increases fastest and its electromagnetic loss increases fastest with the frequency. The electromagnetic loss of Fe-Ga alloy is higher than that of Fe-Co-V alloy in 1~40 kHz and lower than that of Fe-Co-V alloy in 40~60 kHz. The results of this paper provide a basis for electromagnetic loss analysis and high frequency device design of magnetostrictive materials.
