摘要:
油气管道服役时由于内部输送油气会产生压力,使其运行的动态环境发生质变,导致管体结构与内部流体产生耦合等一系列问题。为了克服这些问题有可能对整个管道系统造成的重大危害,以某型油气管道为研究对象,建立了管道流固耦合系统的有限元分析模型,分别研究管道的结构、内腔流场及其流固耦合系统的模态;针对其所处的特殊动态环境,考虑流固耦合效应,进行仿真分析,考察管道耦合系统的整体服役特点。计算结果表明,管道结构的在其低阶模态处表现了较为整体的振型,而在较高的频段内则显示出了大量的局部模态;管道内腔流场的模态振型呈对称分布,耦合系统模态的大部分振型与管体结构较为类似。
Abstract:
When the oil and gas pipeline in service, the transporting oil and gas will produce pressure, it makes the operational dynamic environment occur qualitative change, which leads to a series of problems, such as coupling between pipeline structure and interior fluids.  The above problems are likely to cause significant harm to the whole pipeline system. A FE model of fluid-solid coupling analysis for some type oil and gas pipeline was set up to study the pipeline structure, the fluid modes and the coupling modes. According to the special dynamic environment, considering fluid-solid coupling effect, the simulation analysis was carried out, and the whole service characteristics of pipe coupling system were inspected. The results showed that the structural modes appear a good wholeness at lower frequencies, and appear most local modes at higher frequencies. The fluid modes appear some symmetries. The most modes of coupling modes are more similar to pipeline structure.
