Application of Damping Technique to Vibration Control of Pipelines
摘要
Abstract
The vibration problem of a petrochemical enterprise in Cangzhou is studied. A new type of viscous dampers is used to study the damping technique for vibration reduction of pipelines. Through the site inspection and measurement, it is found that the pipeline segment between the plunger pump outlet and the heat exchanger vibrates violently and the maximum amplitude can reach 1123 μm. Then, the model of this pipeline is established by finite element software and the vibration modes of the pipeline are analyzed. Comparing the results with the actual vibration situation of the pipeline structure, the reason of pipeline vibration is analyzed. Finally, SAP2000 code is used for the simulation of vibration damping so as to optimize the dampers installation scheme. It is found that after the vibration reduction improvement, the maximum amplitude of the pipeline vibration is reduced to 276μm, the entire pipeline operates stably in the safety frequency range and the safety of the chemical production is ensured.关键词
