Determining the Parameters of a Pipe System Containing Fluid Flow by Natural Frequencies of Flexural Vibrations

摘要

The investigation deals with natural frequencies of flexural vibrations in a pipe system containing pressurized fluid flow and clamped at both ends. It has been found that an increase in the axial load results in higher natural frequencies of pipe flexural vibrations. The research has shown that an increase in the pipe wall thickness results in lower natural frequencies of flexural vibrations under tensile axial loading and higher natural frequencies of flexural vibrations under compressive axial loading. It has also been found that an increase in fluid density or pressure within the pipe system results in lower natural frequencies of pipe flexural vibrations.
