Construction of a mathematical model of the vibrational process of pipelines under internal and external loads

Abstract

Abstract The article proposes a modal analysis of the natural vibrations of polyethylene pipelines, which is a calculation of the vertical and lateral pressure exerted by the soil on the pipelines, on the basis of which an oscillation study was conducted in the Ansys software package. The results of modal analysis for polyethylene pipes are presented for a laying scheme with inclined walls and various soils.
