摘要
在进行管线涡激振动快速预测程序或软件开发时,流体力查询匹配问题尤为关键。计算流体力数据的获取需要经过试验或CFD计算,过程十分繁琐和耗时,导致流体力数据的分布难以做到规则和全面。为此文中针对流体力杂乱特点,研究了流体力数据查询插值算法和程序,为海洋管线涡激振动预测软件提供基础。论文实现了反距离加权法的邻域插值算法和三角形插值算法,以及补全数据后的规则数据下的双线性插值算法,并通过算例对各种算法进行了评估,为海洋立管涡激振动快速预测软件开发提供基础。
In the development of the rapid-prediction program or software for the pipeline-based vortex-induced vibration,the query matching for fluid force is critical.The data on fluid force requires test or CFD calculation.The process is very tedious and time-consuming,which makes the data distribution irregular and incomprehensive.This article focuses on the chaotic characteristics of fluid force,and explores the interpolation algorithm and program for fluid-force data query,thus providing basis for the development of the prediction software for vortex-induced vibration in the marine pipeline.The following algorithms are worked out:the neighborhood interpolation algorithm and the triangle interpolation algorithm based on the inverse-distance weight,as well as the bilinear interpolation algorithm targeted at the ruling data and based on the data completion.Various algorithms are evaluated through the calculation examples.These lay a solid foundation for the development of the rapid-prediction software for the vortex-induced vibration in the marine pipeline.
