发电机端部固有频率的模态分析

Mode Analysis of Inherent Frequency at Generator End

通过两例300MW不同机型汽轮发电机的端部固有频率测试及模态参数识别分析,说明发电机端部固有频率测试及模态参数识别是检查发电机端部结构情况的重要手段,并介绍了这两种发电机端部结构模态参数的特点。

Through the analysis on inherent frequency test and mode parameter identification at two 300MW generators end, it is indicated that inherent frequency test and mode parameter identification at two 300MW generators end is important to identify the structure of generator. The mode parameter character at the end of these two generators is also introduced
