BASELINE MACHINERY ANALYSIS DETECTS INCIPIENT DEFECTS

As machinery has become larger, faster, and more complex, the need has continued to grow for vibration analysis techniques which can detect incipient defects sooner and more precisely pinpoint the cause. A technique which has proven to be effective has been called the "baseline' measurement technique. Although similar in approach to standard vibration measurements which rely on general vibration severity guidelines, it goes one step further by using a machines own vibration characteristics as the guidelines. "Baseline" measurements are in reality a set of vibration bench marks for an individual machine against which future measurements can be compared to determine whether there has been any damage or change in the machine's mechanical condition. This article describes the types of baseline measurements that may be performed, that is, overall vibration, frequency analysis, tabular data, and frequency analysis, graphic data. Details that should be followed in order to set up a baseline program are given and discussed, and a few applications of this technique are also included in the discussion.
