海底管线悬空振动的研究现状
|
摘要
海底管线管跨段的涡激振动,是引发海底管线疲劳失效的主要因素之一。介绍了管跨段的形成原因,总结国内外关于管跨段临界长度的计算方法,探讨了近年来对涡激振动问题理论及实验研究的研究现状,提出了在今后的管跨段研究中有待解决的问题。
The vortex-induced vibration(VIV) of span is one of the main factors resulting in fatigue failure of submarine pipe-lines.This paper described the reasons for the formation of free span.It summarized the calculation of the critical length on the free span,and discussed the theory of the vortex-induced vibration and experimental research in recent years.Finally,several suggestions on the free span research are provided.
