摘要
柔性管水动力分析的准确性与保守性直接影响着其疲劳性能计算.文章针对一种非黏结性柔性管,通过OrcaFlex对其进行整体水动力分析,得到载荷曲线;并通过波浪筛选提取典型波浪工况,将其施加到OrcaFlex分析模型中,得到了柔性管各位置处的载荷响应;最后提取了柔性管的最大弯矩和拉伸力数据,为下一步疲劳性能计算提供了数据支持.
Abstract
The accuracy and conservatism of hydrodynamic analysis on flexible pipes directly affect their fa-tigue performance calculation.This paper focuses on an unbonded flexible pipe and conducts an overall hydrody-namic analysis by OrcaFlex to obtain the load curve.Additionally,it extracts typical wave conditions via wave screening and applies the conditions to the OrcaFlex analysis model for obtaining the load response at various posi-tions of the flexible tube.Finally,the extracted maximum bending moment and tensile force data of the flexible pipe can provide data support for following fatigue performance calculation.
