摘　　要：某汽轮发电机组带负荷过程中,高负荷工况中压转子两端支撑轴承存在无规律的振动波动问题,轴振波动以工频分量为主、无杂频分量。分析原因并采取相应措施后,消除了异常振动波动问题,保障了机组的正常安全运行。A turbulent vibration problem is investigated in the shaft vibration of intermediate-pressure rotor at high load condition during the load-increasing process of a steam turbine-generator unit.The rotating frequency of shaft dominates the turbulent vibration without any other messy frequency.Based on the cause analysis and application of the corresponding measures,the abnormal vibration problem is eliminated and the safe operation of the steam turbine-generator unit is ensured.
