Study on the vibration of pipelines caused by internal pulsating flow

Vibrations of pipelines caused by internal pulsating flows are calculated by the transfer matrix method. The transfer matrices for static and dynamic transformation are constructed from the equatios of a curved pipe element conveying fluid. Applying boundary conditions, equilibrium points, complex natural frequencies and mode shapes are calculated. Experiments were carried out for vibrations of simple pipelines caused by internal pulsating flows. The calculated natural frequencies of the pipeline systems show good agreement with those obtained by the experiments.
