摘要
本文采用基于等参单元的双标量位法计算三维静磁场,推导了六面体等参单元的离散格式,用此方法计算了回旋加速器的三维静磁场和变压器的三维恒定漏磁场,所得结果可供工程参考.
The two-scalar-potential method is applicable to the solution of the three-dimension (3D) magnetostatic field problems. The diseretization formulae with the isoparametric hexahedron element are derived. The 3D magnetostatic field for a 1.2M cyclontron, and the 3D leakage field of a 17000KVA power transformer are calculated, and the results are in good agreement with measured values.
