摘　　要：介绍了一种先进的VIV(涡激振动)评估方法,这种方法通过构建管道数字孪生体,可以对一系列河流穿越场景进行模拟评估,包括传统分析方法难以解决的带配重块的管道穿越河流情况。为VIV提供了更好的管道响应预测,以支持完整性评估。此外,对于现有CFD(计算流体力学)分析方法和经验方程进行了进一步的补充和发展,通过数字孪生技术、FSI(双向流固耦合技术)样本应用案例研究,展示了该技术如何同时捕捉流体动力学和结构响应的耦合变化,从而同时考虑稳定和不稳定振动情况。这些结果说明新型的河流穿越VIV评价对管道的完整性过程管理具有一定贡献。This paper presents an advanced vortex-induced vibration(VIV)evaluation method,which provides VIV with better pipeline response prediction to support integrity evaluation by constructing pipeline digital twins to simulate a range of river crossing scenarios,including pipeline crossing situations with river weights that are difficult to solve with traditional analysis methods.Additional details on the existing computational fluid mechanics(CFD)analysis and empirical equations are also presented.A sample application case study of digital twin technology and bidirectional fluid structure coupling technology(FSI)demonstrates how the technique captures coupled changes in fluid dynamics and structural response simultaneously so that both stable and unstable vibration conditions are considered.These results are used to demonstrate how the advanced VIV evaluation can contribute to pipeline integrity water crossing management.
