【 摘 要 】

There are many tools available to help diagnose equipment vibration problems around the Savannah River Site. With the advancement of technology surrounding vibration analysis, modal analysis, an old, proven engineering modeling technique, can now be performed using the multi-channel machinery analyzer found in most predictive maintenance programs. The use of modal analysis can help eliminate problems with plant equipment that include failure to maintain tolerances, noisy equipment operation, material failure, premature fatigue, and shorten equipment life. Mark H. Richardson of Vibrant Technology Inc., the creator of the MeScope Modal Analysis software program, defined modal analysis as the process of characterizing the dynamics of a structure in terms of its modes of vibration. Knowing the modes of vibration of a structure is useful information in itself, for it tells at what frequencies the structure can be excited into resonant motion, and the predominant wave-like motion it will assume at a resonant frequency.
