The reduction of elevated dynamic loads, affecting the elements of the hydraulic drive, is an important task in production equipment maintenance. In case of the hydraulic drive with actuators, remotely located from the power source, the piping defines the working capacity of the whole system. Hence the development of piping vibroacoustic analysis methods appears to be the vital task. The said methods would not only help to define the cause of increased loads, but also permit to develop an adequate design solution without prolonged experimental checks.The article proposes the method of pipeline system vibroacoustics analysis through the example of press-forge unit drain piping. The novelty of this method consists in the use of the fluid pulsation and piping vibration spectra analysis in their correlative comparison with account to the calculated modal parameters of a pipeline.The measurements of working fluid pressure pulsation and pipeline vibration in the vicinity of the breakage locations were carried out. The experimental data spectrum analysis indicated an apparition of intense water-hammer process along with the frequency coalescence of fluid pulsation and pipeline vibration. The resonant vibration amplification, caused by the water-hammer effect, was suggested. The pipeline system mathematical model, allowing to calculate its modal parameters, was derived. The comparison of the modal analysis with the vibroacoustic response confirmed the hypothesis of the pipeline resonant breakdown.The article depicts, that the study of the pipeline system vibroacoustic response, based only on Fourier analysis of the working fluid pulsation and pipeline vibration, is prone to fail the reliable causation of elevated dynamic loads. It is suggested to complement the vibroacoustic response analysis with the modal parameters calculation. The mathematical computation of the modal frequencies and shapes was implemented instead of their experimental observation in order to exclude the undesired signal, introduced with attached mechanical equipment. On top of that, the mathematical computation of the pipeline modal parameters allowed to perform the pipeline modal frequency shift from the water-hammer effect frequency range through cautious relocation of additional supports.
