摘要

考虑到晶粒取向电工钢的二维磁性能，研究了有效各向异性张量磁导率，并提出了一种计算效率高的响应面法(RSM)平滑二维磁性能的算法。结果表明，在非线性磁场分析中，重构的二维磁场性质对于稳定牛顿-拉夫森迭代的收敛性是相当有效的

A Computationally Efficient Finite Element Analysis Algorithm Considering Two-Dimensional Magnetic Properties

For taking account of the two-dimensional magnetic properties of grain-oriented electrical steel, the effective anisotropic tensor reluctivity is examined, and a computationally efficient algorithm is suggested by using response surface method (RSM) to smooth the two-dimensional magnetic properties. It is shown that the reconstructed two-dimensional magnetic properties are fairly effective to stabilize the convergence of the Newton-Raphson iteration in the nonlinear magnetic field analysis
