- Abstract
The statistical properties of multidimensional diagnostic features, the locations and amplitudes of discrete components in the power spectra of vibration-acceleration envelopes that characterize incipient flaws in mechanisms, have been studied. Experimental data have been processed. Using a nonparametric rank correlation test, the mutual and combined independence of the one-dimensional values of multidimensional feature quantities has been proved. The distribution laws for these features have been researched using the Kolmogorov-Smirnov nonparametric test. It has been taken that in the general case, the distribution laws for these features can be of any form.
