Фрагмент статьи
Vibration-based symptoms are extremely important in monitoring technical condition of virtually all types of rotating machinery, especially large and complex units, e.g. turbo-generators, large fans or compressors. This is justified by their high information content, non-intrusive nature and comparatively well-developed data acquisition and processing procedures. The most straightforward approach consists in analyzing vibration patterns recorded at a certain moment on the basis of a purpose-developed diagnostic model. Information on the object condition is, however, also contained in time histories of certain vibration components. As pointed out in References, a vibration component evolution type and relevant timescale (the latter varying within a broad range, from seconds to months) contain information on a fault type and thus are useful already at the qualitative diagnosis stage. More detailed analysis of vibration time histories becomes even more important when it comes to quantitative assessment and is mandatory for a prognosis.
