摘要
对天生桥一级电厂3#机组上机架异常振动进行了真机实测及原因分析,得到的结果是:振动过大的主要原因是发电机转子质量不平衡,次要原因是机组轴线不直。并通过上机架有限元计算从理论上得到了证实。
For prototype test and vibration source analysis on abnormal vibration of 3 # hydro generating set at Tianshengqiao first cascaded power station, it is useful to find out the vibration source by finite element computation for upper bracket. It is found out and proved under the direction of theory that the vibration source is unbalanced generator rotor and curved main axis of the set.
