EXPERIMENTAL STUDY OF DYNAMIC PARAMETERS OF COMPLEX PIPELINE SYSTEM
The article discusses the results of studies of the dynamic parameters of a pipeline connected to a pump, carried out in order to obtain data in full-scale conditions. At this stage of the study, the stationary process of the pump operation, which forms a turbulent flow in the pipeline, was studied. A computational and experimental technique for studying natural frequencies and vibration modes of pipelines of complex spatial configuration has been developed. The adequacy of the developed methods of finite element modeling of dynamic processes in pipeline systems in the frequency range up to 400 Hz has been confirmed.
