【摘要】 采用有限元计算与试验模态分析相结合的研究方法，对３００ＭＷ汽轮发电机的主要部件（机座）和整机进行模态分析，以确定合理的结构离散化数学模型，然后对发电机的振动进行实测，为其结构的改进设计提供依据。更多还原

【Abstract】 To determine the reasonable discrete mathematical model of generator structure,the research technique combining finite element method and test model analysis is adopted for model analysis of frame and global structure of 300 MW turbo-generator respectively. Vibration of generator is measured and analyzed for modification.更多还原
