摘　　要：分析某电厂汽轮发电机组产生半频振动故障的主要原因,围绕提高轴瓦工作稳定性和降低激振力两个方面进行处理,对机组轴瓦瓦面修刮和现场高速动平衡试验,最终振动问题得到解决,为同类振动故障诊断提供借鉴。The main cause of a half-frequency vibration fault in a steam turbine-generator set is analyzed in this paper. Aiming at improving bearing stability and reducing unbalancing forces in the steam turbine rotor, the vibration problem is successfully resolved through bearing scraping and field high-speed dynamic balancing test. which gives a reference to the diagnosis of the similar problem.
