Research On The Diagnosis And Treatment Methods Of Rotating Mechanical Vibration In Nuclear Power Plant Commissioning Period

During the commissioning period of nuclear power plants, vibration problems occurred frequently. In this paper, a certain nuclear power plant was taken as the analysis object. It was found that adopting reasonable vibration diagnosis and treatment methods is conducive to accurately locating and solving vibration problems of rotating machinery, such as false feet, insufficient stiffness, resonance, and misalignment, with less economic and time investment, thereby ensuring the safe operation of nuclear power plants.
