1000MW核电机定子机座及铁心固有频率有限元计算分析

3D FEM Analysis of Natural Frequency of Stator Frame and Core for 1000MW Class Nuclear Generator

东方电机股份有限公司生产的1000MW级核能发电机定子机座、铁心的固有频率、模态振型进行了三维有限元动力特性计算分析。这对于了解核电发电机定子系统的动力特性、开发大型汽轮发电机、设计制造及安全运行等都具有重要意义。

3D FEM analysis of natural frequency and modal shape on 1000 MW nuclear generator stator frame and core are presented. These are important for knowing the dynamical characteristic of the nuclear generator stator, developing large steam generator as well as its designing, manufacturing and safe operating.
