Abstract
AbstractIn oil transportation stations, the plunger motion exhibited by positive displacement pumps can cause a great deal of vibration that can influence the secure operations of the equipment and pipelines. If resonance between the equipment and pipelines occurs, their integrity can be compromised, resulting in catastrophic damage. Therefore, both stress analysis and vibration analysis are necessary before a pipeline is formally put into operation. For this study, mechanical models of pipelines and constraints in positive displacement pump pipeline systems, based on theories of stress and vibration in pipelines, were created. Numerical simulations, including stress, modal, and vibration analyses were performed on-site at an oil transportation station in west China. The data were collected, reported, calibrated according to published standards, and then analyzed. The results revealed that the models created were reliable for stress and vibration analyses of pipelines in practical applications and that re...
