Physical modeling of pipeline resonance in civil buildings

Abstract

The method of experimental determination of the magnitudes of pipelines resonant vibrations on small-sized physical models of 1:10 of actual size is shown. The measured values of the oscillation frequencies of pipe models with hinged and pinched supports on both sides are compared with their mathematical counterparts. Fluctuations of pipes with clogging allow us to determine its effect on the values of the resonant frequencies. The obtained results are essential for predicting accidents and fatigue failures of pipelines for various purposes. During the tests on steel models, the excited harmonic sound oscillations of the models are captured by an electromagnetic transducer and transmitted through a microphone amplifier to a computer that serves as an oscilloscope.
