| Summary: | In operation, research results are presented in the field of technical
diagnostics and are related to detection and examination of
new faults diagnostic signs on the basis of vibroacoustic signal
characteristic function parameters. The obtained signs are integral
estimates of the vibroacoustic signals statistical characteristics
for piston compressors. The paper presents the boundary values
of diagnostic signs based on the parameters of the area under
the curve of the vibroacoustic signals characteristic function
modulus. The decision-making risk curves were constructed, the
probabilities of missing a malfunction and a false alarm were
calculated for the selected values of diagnostic signs. The use
of suggested signs makes it possible to increase reliability of
technical devices condition monitoring and their diagnosis. |
