Full pipeline oscillation model under impact

Abstract

An urgent task is to obtain experimental data on pipeline vibrations to assess the effectiveness of vibro-acoustic methods
for monitoring its condition, while access to the object is often difficult. The paper presents an improved model, on the basis of
which it is proposed to calculate the elastic oscillations fixed on the surface of the pipeline as a result of impact. The assessment of the adequacy of the obtained analytical expression is carried out by comparing the calculated signal with the empirical one obtained on the active object.
