Method development of the vibroacoustic characteristics calculation of the gas distribution stations elements.

Pressure-reducing devices such as protective valves, control valves and chokes can create high levels of high-frequency acoustic waves at the outlet of the valve. These acoustic waves are propagated along the pipe, thereby generating vibrations, which in turn lead to fatigue failures, sometimes malfunctions set in within a few hours. In this research work, we have studied the main approaches of the vibroacoustic characteristics analysis that as a result has allowed us to develop the method of calculation of vibroacoustic characteristics, which would help to make the assessment of pipeline strength, of pipes noise and vibration levels more practicable. At this method different ways could be employed to get the desired results depending on the kind of data (measured vibroacoustic characteristics, geometric characteristics of the element, the input parameters).
