摘要

针对考虑磁滞特性时步有限元法中磁阻率选取不当，导致非线性迭代无法收敛的问题，提出一种通过设置阈值，并在每个时间步动态改变收敛因子的磁阻率选取方法。首先，基于固定点法建立关于矢量磁位和励磁电流的二维磁场有限元方程，引入定点磁阻率处理材料非线性问题；其次，根据电磁感应定律建立磁场-电路耦合关系，并采用Jiles- Atherton磁滞模型表征铁心的磁滞效应，从而形成考虑磁滞的场路耦合模型；再次，引入阈值解决非线性迭代过程中的收敛难题；最后，利用该方法求解非晶合金-取向硅钢组合铁心的励磁电流、磁通密度分布以及空载损耗，并通过实验验证所提方法的有效性。

Abstract

To address the non-convergence issue in nonlinear iterations caused by improper reluctivity selection during hysteresis-aware time-stepping finite element analysis

this paper presents a magnetic reluctivity selection method. The proposed approach dynamically adjusts the convergence factor at each time step by setting a threshold

thereby stabilizing the iteration process. First

the two-dimensional magnetic filed finite element equation of magnetic vector potential and excitation current is established using the fixed-point method

and the fixed-point permeability is introduced to address the nonlinear issue. Second

the field-circuit coupling relationship is established based on the electromagnetic induction law

and the Jiles-Atherton hysteresis model is utilized to characterize the core’s hysteresis characteristics

thus a field-circuit coupling model considering hysteresis is formed. Then

the threshold is introduced to solve the convergence difficulties in the nonlinear iterative process. Finally

the effectiveness of the proposed method is verified by applying it to a composite core made of amorphous alloy and grain-oriented silicon steel

from which the excitation current

magnetic flux density distribution

and no-load loss are successfully computed.
