| 摘 要： | 针对油气管道中存在的管跨现象,为实现管跨破坏的早期预警,文章提出一种基于弹性波监测管跨的新思路。鉴于油气管道中的弹性波传播问题,应用有限元分析方法,将管道结构简化为一维弹性直杆模型。采用ADINA软件对弹性波在管道中的传播过程进行有限元分析,得到了典型节点的位移—时间历程和典型单元的应力云图,计算结果表明该方法可行。开展基于弹性波监测的油气管道管跨定位研究,可为油气管道安全预警技术研究提供参考,工程实用价值较大。

| Abstract: | Regarding the pipeline span phenomena existed in oil and gas pipelines, this paper proposes a new thought of pipeline span locating based on the elastic wave detection in order to implement an early alert for pipeline span destruction. Aimed at the problem of elastic wave propagation in oil and gas pipelines, the finite element method is applied to the simplified model of one-dimension elastic straight bars for modeling pipeline structure. By using ADINA software, the FEM analysis on elastic wave propagation in oil and gas pipelines was carried out. The displacement-time history relation for typical nodes and the stress nephogram for typical elements are obtained. The calculated results show that the method is viable. |
