大型汽轮发电机转子端部三维涡流场数学模型

THE MATHEMATIC PATTERN IN THE EDDY CURRENT MAGNETIC FIELD AT THE END OF THE ROTO R OF TURBOGENERATOR

以汽轮发电机转子端部涡流场的数学模型为例 ,论述了采用 A,Ф— A法 ,将三维涡流场有限元计算 ,引入汽轮发电机转子端部三维涡流场的分析中 ,并入了库仑规范 。

The article is about the foundation of the mathema tic model in the eddy current magnetic field at the end of the rotor of turbo generator. By using A,Ф—A method, the finite element method is used in analyzing the trinity eddy current magnetic field at the end of the rotor of tur bo generator. The related equations for finite element method are given.
