本文计算了水轮发电机定子铁心的等效工程弹性常数,通过利用计算得到的铁心叠片等效工程弹性常数对其进行屈曲分析,并将屈曲分析结果与传统的理论计算结果进行比较,从而说明当把计算得到的弹性常数作为输入参数时,有限元方法的模拟结果符合发电机的实际安装运行情况。
In this paper, we study the problem of effective engineering elastic constants of hydro generator stator core, and have a buckling analysis on the stator core by utilizing the obtained effective engineering elastic constants of stator core lamination, then compare the simulative results with the theoretical results, we know when the elastic constants are used as the import parameters, the results obtained by the t-mite element method and the actual case is consistent.
