摘要

本文提出了一种基于磁标量势体积积分法(MSP-VIM)的求解三维非线性静磁问题的改进方法。将矩量法生成的阻抗矩阵分为常数部分和非线性部分。在此基础上,利用多阶奇异值分解(MLSVD)对常量部分进行进一步压缩。此外,对对称结构进行简化计算,减少了未知量,降低了矩阵维数。从而使非线性问题的迭代求解变得简单快捷。数值算例验证了该方法的准确性和有效性。

Application of Magnetic Scalar Potential Volume Integral Method in Nonlinear Magnetostatic Problems
This paper describes an improved method based on the Magnetic Scalar Potential Volume Integral Method (MSP-VIM) to solve 3-D nonlinear magnetostatic problems. The impedance matrix generated by the Method of Moment (MoM) is separated into constant part and nonlinear part. Moreover, the constant part is further compressed with Multilevel Singular Value Decomposition (MLSVD). Besides, the simplified calculation for symmetrical structure is applied to decrease the unknowns and reduce matrix dimension. Consequently, the iterative solution of nonlinear problems becomes easy and fast. The accuracy and efficiency of the proposed method are demonstrated by numerical examples.
