Interpretation of Bearings Vibrations Vibrospects of Gas-Pumping Units by Self-Organizing Systems Methods
The article is devoted to the development of special methods for forecasting accidents of gas-pumping unites (GPU) based on the interpretation of the vibrational spectra of the oscillations of the low-pressure turbine thrust bearing housing (PMO TND) body case. When developing a complex defect, it is proposed to use the value of the correlation dimension, determined on the basis of the one-dimensional frequency range of the measured vibration velocity of the housing of the GUP TND GPA, as an additional criterion. It is shown that in the defect-free state of the gas pumping unit, the dependence of the correlation dimension of the strange attractor (v) on the dimension of the enclosed space ( m ) has the form of a curve with saturation and in the corresponding coordinates goes to the asymptotic horizontal boundary. If there is a danger of an emergency failure, then the saturation of the function v (m) is not observed in the entire research area, the correlation dimension v (m) increases monotonically with the enclosed space increasing dimension.
