摘　　要：软磁材料的非线性磁化特性使得软磁带材涡流场分布及其损耗特性分析十分困难。为此,该文采用分段线性的方法对基本磁化曲线进行逼近,基于麦克斯韦方程在每个线性段进行推导,得到单频正弦激励下软磁带材中与涡流损耗相对应的平均磁场强度Hcl表达式,并提出相应的参数辨识方法。进而,基于场分离技术与损耗分离的一致性原理,建立场分离形式的高频动态磁滞模型。根据实际应用中的高次谐波特征,基于磁导率的近似线性特征和场量的叠加原理,构造描述多谐波激励下与涡流损耗相对应磁场强度Hcl的解析表达式,并进一步提出软磁带材在复杂多谐波激励下的动态磁滞预测模型。通过实验结果与仿真结果的对比,验证该文所提方法的有效性和准确性。The nonlinear magnetization characteristic of soft magnetic materials makes it difficult to analyze the distribution of eddy currents and their loss characteristics in soft magnetic tape materials.Therefore,a piecewise linear method is used to approximate the basic magnetization curve.Based on the derivation of Maxwell's equations in each linear segment,the expression of the average magnetic field intensity Hcl corresponding to eddy current loss in soft magnetic tape materials under single-frequency sinusoidal magnetization is obtained,and the corresponding parameter identification method is proposed.Furthermore,based on the consistency principle of field separation technology and loss separation,a high-frequency dynamic hysteresis model in the form of field separation is established.In accordance with the high-order harmonic characteristics in practical applications,a calculation method for the magnetic field intensity Hcl corresponding to eddy current loss under multi-harmonic excitation is constructed based on the approximate linear characteristics of permeability and the superposition principle of field quantity,and a dynamic hysteresis prediction model for soft magnetic tape materials under complex multi-harmonic magnetization is further proposed.The effectiveness and accuracy of the method proposed in this paper are verified by comparing experimental results with simulation results.
