The influence of environmental factors on spread оf elastic oscillations in pipeline

Abstract

To improve active vibro-acoustic systems for monitoring condition of pipelines, the actual task is to adapt them to changing
environmental conditions. The influence of soil moisture, frequency of elastic vibrations and depth of pipeline immersion on the damping elastic oscillations by means of factor experiment and regression model, which made it possible to estimate the mutual influence of factors on elastic oscillations in the pipeline, is studied. The frequencies of the amplitude spectrum of the signal with the maximum absorption of ground are singled out, the use of which in the monitoring systems will allow to detect the change in the properties of the contacting environment.
