管道流致振动的定量评估方法研究
Study on quantitative evaluation method of flow-induced vibration in pipelines
摘要
Abstract
Flow-induced vibration(FIV)may lead to fatigue failure in piping systems.Therefore,controlling FIV is crucial during the engineering design and operation stages.Currently,piping design in traditional projects is normally based on static analysis,without considering the fatigue damage caused by flow-induced vibration in pipelines.As a result,vibration analysis and corrective measures are typically conducted only after FIV occurs.This paper details the evaluation criteria and procedures for quantitatively evaluating flow-induced vibration in pipelines at the design stage.Taking a two-phase flow pipeline in a desulfurization unit of a natural gas purification project as a case study,the analysis illustrates the evaluation process,and proposes corrective measures for pipelines with high risk,which proves to reduce the risk of fatigue failure caused by FIV.The research results provide valuable technical references for mitigating the impact of flow-induced vibrations in engineering applications.关键词
