弹性作为软材料的一种固有性质，受到交变磁场的影响。利用激光磁致伸缩测量系统测量了取向硅钢在直流偏磁和多正弦磁化下的磁致伸缩特性。获得了不同磁化强度下GO硅钢片的磁致伸缩曲线，并根据测量数据观察和分析了频率和直流偏压对GO硅钢片磁致伸缩性能的影响。此外，磁致伸缩下的谐波磁化的频谱，并在直流偏置和multitisinusoidal磁化下的磁致伸缩引起的A加权分贝值表示的GO硅钢片的声学噪声水平进行了测量。将测量结果应用于三柱叠片铁心模型的仿真，分析了直流偏磁和谐波对磁通密度和位移的影响。
As an intrinsic property, elasticity of soft material is affected significantly by the externally applied alternating magnetic field. Magnetostrictive properties of the grain-oriented (GO) silicon steel under DC-biased and multisinusoidal magnetizations are measured by using a laser-based measuring system. Magnetostriction curves of the GO silicon steel sheet under different magnetizations are obtained and the influence of frequency and DC bias on the magnetostrictive property is observed and analyzed based on the measured data. In addition, the spectrum of magnetostriction under harmonic magnetization is obtained, and the acoustic noise level of the GO silicon steel sheet represented by the A-weighted decibel value caused by magnetostriction is measured under DC-biased and multisinusoidal magnetizations. The measurement results are applied to the simulation of the three-limb laminated core model, and the effects of DC bias and harmonics on magnetic flux density and displacement are analyzed.
