Abstract
Parametric resonance at asymmetric vibrations of the cylindrical shell of the gas-discharge barrel made of a thermoplastic polymer pipe "Furanflex»
Incoming article date: 24.01.2020The article presents theoretical calculations and studies of the possibility of parametric oscillations and parametric resonance arising in a polymer self-supporting thermoplastic pipe "Furanflex". Тheoretical calculations of the possibility of asymmetric parametric oscillations and parametric resonance are considered.The Furanflex thermoplastic, polymer liner is offered as a variant of a separate gas exhaust trunk during the reconstruction of boiler rooms and thermal power plants by heat generating companies.The description and calculation of resonant phenomena for asymmetric parametric oscillations are described in detail.Detailed mathematical transformations of differential equations of parametric oscillations are given.The article provides a detailed description and analysis of the occurrence of parametric oscillations. Examples of symmetric and asymmetric parametric oscillations are considered.Information and conclusions of the presented work are intended for a different range of readers, teachers, designers, students of construction specialties.This article should be of interest to utility managers and heat generating companies .
