摘要
四川省五通桥发电厂一台 N50／90 型汽轮机发生异常振动。经试验分析为汽轮机转子 X／2 型亚谐共振，经缺陷处理后振动消除。文中介绍机组振动情况、产生的原因及消除振动的措施。
： Abnormal vibration occurred on one N50／90 type steam turbine in Sichuan Wutongqiao Power Plant． Through testing and analysis， it was thought of to be X／2 type subharmonic resonance of steam turbine rotor． After the defect was eliminated， vibration disappeared． This paper introduces the vibration status of steam turbine ， causes for vibration－occurring and elimination measures of vibration．
