It was theoretically proved and practically confirmed that vibration parameter trends develop according to an exponential model on the areas of catastrophic wear of equipment. The practice of vibration analysis showed that different defects develop at different time intervals.
Consequently, the stage of catastrophic wear of different units takes different periods of time. Thus, the duration of exponential growth of vibration parameter trend is determined by the type of defect or malfunction associated with wear at a time (i.e., the type of wear process).
From the above reasoning it is possible to carry out vibration analysis of the equipment condition by determination of the rates of growth at different time intervals (at different areas of the trend), which correspond to different defects and stages of their development. Excess of the rate of growth at a certain area indicates hazardous development of corresponding defect or malfunction.
