摘　　要：针对国产125 MW机组发电机后轴承异常振动的问题,在深入试验研究而取得大量现场试验数据的基础上,应 用转子动力学的研究成果,并结合多年现场工作经验,对125 MW机组发电机后轴承异常振动的机理进行了剖析,提出 了解决的途径。实践证明,该分析和处理方法是行之有效的。For the problem of abnormal vibration in rear bearing of domestic 125 MW generator, based on a lot of field-test data and practice of many years, using research results of rotor moving dynamics, the mechanism of abnormal vibration in rear bearing of generators is analysed, the way to solve this problem is suggested. Practice shows that both the analysis and the solving way are effective.
