Improving the quality and reliability of aviation equipment is impossible without correct information on its technical condition at all stages of life cycle: in developing in design office, at the manufacturing stage and in operation. Information on present, past and future technical condition of a product is obtained by the methods of technical diagnosis, genesis and prediction.
The quality of these methods is characterized by PD probability of acquisition of correct information on the product condition at a time. Vibration monitoring of condition integrates these methods into a single continuous process by the elimination of passing through the time intervals with unobserved changes of the condition.
Reliability of the results of monitoring (PM) is determined not only by the reliability of vibration analysis (PD), but also by the frequency of vibration control (TK) that should be considerably smaller than duration of malfunction development (TN) because it determines the probability of detection (PT) of a critical malfunction.
