摘　　要：介绍大型工业汽轮机的１种异常振动现象，通过对该汽轮机长期监测，分析出汽轮机无规律间歇振动的主要原因是相对超负荷、流体力以及质量不平衡等因素综合作用的结果，并介绍相应对策实施后的效果。Abstract This paper introduces a kind of abnormal vibration phenomenon of a large-scale in-dustry steam turbine. By supervising and testing for a long time , the main reason forthe irregular intermittent vibration of the steam turbine has been analysed. It was thecomprehensive action with relative over-load and fluid force and imbalance that causesthis kind df vibration. In addition,the effect after carrying out some relevant counter-measures is also introduced in the paper.SUBJECT TERMS : intermittent vibration, steam turbine, imbalance, compressor,ro-tor
