摘要
本文首次提出电机饱和磁场的无内节点亚参三角形有限元计算问题,并给出了构造其形状函数的有效方法。同时,结合电机电磁场计算实例,证实了这种新的有限单元能够满足工程计算的精度要求。
First the paper addresses the problem that subparametric triangular finite elements without inner points are used to calculate the saturated magnetic fields in electric machines. An effective method for making shape functions for the new finite elements is also given. The computation trials show that the accuracy of computation achieved by these methods is satisfactory with in the requirements of electrical engineering.
