在标准有限元(FE)模型中考虑具有涡流和磁滞的完全耦合层压模型在实施工作量、存储器要求和计算时间方面是极其昂贵的。因此,本文利用代数近似的叠层模型作为传统的本构关系,在二维有限元模拟旋转电机。提出了参数化模型结构和参数的提取以及均匀化有限元特征的迭代自适应。这种务实的方法被证明是相当准确和有效的,同时允许通过在完全耦合的层压模型和宏观模型之间迭代来细化预定的参数表达。
Consideration of a fully coupled lamination model with eddy currents and magnetic hysteresis in standard finite element (FE) models is prohibitively expensive in terms of implementation effort, memory requirements and computation time. Hence this paper utilizes an algebraic approximation of the lamination model as a conventional constitutive relationship in two-dimensional FE simulations of rotating electrical machines. Extraction of model structure and parameters of the parametric model as well as iterative adaption of the homogenized FE characteristic are presented. This pragmatic approach turns out to be quite accurate and efficient simultaneously allowing for refinement of the pre-determined parametric expression by iterating between the fully coupled lamination model and the macroscopic model.
