| 摘 要： | 建立了上机架-定子耦联模型进行模态分析,考虑了定子铁芯和机座的热态工况。通过调整设计变量参数,进行灵敏度计算。结果表明,上机架立筋为最大影响因素,且系统频率并不随立筋厚度增大而持续增大,即存在极值点。

| Abstract: | The modal analysis on upper bracket-stator system is established,considering stator frame and stator core in thermal state.By the adjustment of the parameters,the frequencies are various.The results show that the most important effect factor is the thickness of the vertical steel of upper bracket and the frequency doesn't increase continuously through the enlargment of the thickness of the vertical steel structure,an extreme point existed. |
