The Vibroacoustic Characteristics Research of the Gas Pipeline

Technical focus of the research is a discrete throttle valve (DTV) and gas pipeline. An extensive research of vibration and acoustic characteristics of the main pipeline of a gas distribution station was carried out. The acoustic noise power level radiated by the main gas pipeline and it's comparison with the strength criterion were made. The levels of vibration acceleration in different parts of the main gas pipeline were measured. On the basis of experimental data the possible causes of the acoustic-induced vibration are described, and measures for reducing vibration loading of a gas pipeline were proposed.
