摘　　要：根据三峡水库水位上升左岸6F和右岸21F运行稳定性试验结果,分析了机组过流通道中水压力脉动变化规律及其对机组振动和厂房振动的影响,并讨论了6F和21F在涡带工况区和高负荷区中的不同振动现象。研究结果表明,有助于对机组性能进一步深入分析和指导机组安全运行。According to the result of the operational stability test of Unit No. 6 at Three Gorges Left Bank Power Plant and Unit No. 21 of Right Bank, this article analyses the change rule of the water pressure pulsation in the fluid passage as well as its influence to the vibration of the units and the powerhouse. Also it discusses the different vibration phenomena of the Units No. 6 and No. 21 working under the vortex core condition and the high load condition. The study result shows that it is useful to the developing research of the units＇ capability and supervise the units＇ safety operation.
