- 摘要:
- 流致振动现象可能造成管道疲劳破坏,因此在设计和运行过程中,对流致振动的控制至关重要。传统工程设计中,管道都是基于静态分析设计,未考虑管道流致振动带来的疲劳破坏问题,出现问题后才进行分析与整改。详细阐述了在设计阶段对管道流致振动进行定量评估的判定标准及流程,以某天然气净化项目脱硫装置中两相流管道为例进行分析,对风险较高的管道提出整改措施,经验证，整改措施可有效降低流致振动导致管道疲劳破坏的风险。研究成果对降低工程中管道流致振动的影响具有一定借鉴意义。
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.
