A Vibroacoustic Method for Diagnosing the Influence of Impulse Load on Fiberglass Pipes

An algorithm for studying the change in the technical condition of pipelines made of fiberglass with a diameter of 75 and 130 mm during operation and the accumulation of damage in the pipe wall by the vibroacoustic method is considered. The effect of dynamic loading and damage accumulation (microcra...

Zusammenfassung:	An algorithm for studying the change in the technical condition of pipelines made of fiberglass with a diameter of 75 and 130 mm during operation and the accumulation of damage in the pipe wall by the vibroacoustic method is considered. The effect of dynamic loading and damage accumulation (microcracks and their development) were evaluated on the basis of the change in the magnitude of the amplitude–frequency shift before and after a certain test cycle. The boundaries of the change in performance in the amplitude–frequency region for pipes made of polymer-composite materials have been established.
