Abstract

DOI: https://doi.org/10.26565/2079-1747-2025-35-01

The article considers aspects of an integrated approach to vibration inspections of gas transportation equipment. A critical analysis of scientific literature and regulatory documents covering existing approaches to solving issues related to determining the actual technical condition of equipment, assessing its service life, and making decisions on extending its service life has been carried out. The application of vibroacoustic research to solve control problems has been analyzed by studying the scientific literature. Dynamic and mathematical models of gas transportation equipment have been developed, particularly models of the general level and harmonics of the vibration velocity spectrum of bearing housings, models of oscillations of the centrifugal supercharger housing at the rotor blade frequencies, models of the force generated by the turbine or compressor blade stage of a gas turbine unit transmitted to the rotor, and models of gas pressure pulsation in the pipe. The modeling has been performed using the developed dynamic and mathematical models. The analysis of the modeling results, corresponding to the results of experimental studies, has been presented.
