Randomized filtration in the problems of equipment vibration analysis

In order to create faultless systems for vibration analysis and vibration monitoring in conditions of a priori uncertainty concerning the parameters of the signals, noise and the types of diagnosed units it is necessary to solve the problem of the signals filtration under conditions of correlated noise.

In such a case auxiliary independent random variable is usually introduced. By means of this variable the correlation between averaged values is eliminated through a random selection of these values according to 0 or 1 value of auxiliary random variable.

The paper presents the method and system of increase of reliability of the results of vibration analysis and vibration monitoring by randomized averaging of certain diagnoses with detection of randomizing characteristics by vibration parameters of diagnosed machine on the basis of extreme characteristics of spikes of vibration phase.
