| 摘 要： | 本文对计算三维静磁场的等效磁化区法作了研究,从理论上证明了用等效磁化区方法计算三维静磁场的正确性,并提出了构成等效磁化区的一般方法。按照等效磁化区法的数学模型,本文对用有限元方法求解三维静磁问题的离散格式作了推导,并研究了用等效磁化区法计算非线性磁场的途径,给出了按牛顿-拉斐逊法求解非线性方程组的雅可比矩阵。应用所编的PORTRAN程序,本文计算了飞轮式永磁发电机的空载和负载三维静磁场,并对电机的端部磁场作了测量。结果表明,计算值与测量值之间虽存在一定误差,但磁密的变化趋势两者基本一致。

| Abstract: | The validity is theoretically proved,a genera] procedure suggested for construction of equivalent magnetized region.Based on mathematical model of the method,finite element discretization is derived for solving three dimensional magnetostatic field problems,the effectiveness of the method on nonlinear problems discussed, and Jocabi matrix for iterative solution of nonlinear equations given. Finally, a FORTRAN is programmed and applied to the analysis of magnetostatic field under load or no load on flywheel type magneto,and flux density at the ends of the magneto measured, Results show that calculated values are basically in agreement with measured ones. |
