Measurement of vibrations of a pipe system

Abstract

The two dimensional system of pipes is investigated. The model of a pipe system consisting from two dimensional beam s by taking the inertia of fluid filling the pipes into account is used and the eigenmodes are determined. The places of the pipe with small amplitudes of vibrations and with large amplitudes of vibrations for the eigenmodes are determined. Then the p laces where the amplitudes for several first eigenmodes are large are determined. In those places it is recommended to perform measurements of vibrations of the pipe system.
