摘要/Abstract

摘要： 为有效预测多因素作用下深海立管涡激振动(VIV),首先,基于欧拉-伯努利梁弯曲理论和改进范德波尾流振子方程,考虑管内流动流体和立管横向(CF)和顺向(IL)耦合作用,建立海洋立管涡激振动预测模型,用埃尔米特插值函数离散立管微分方程,纽马克-β法在时域内迭代求解立管位移;然后,设计VIV试验,并将试验数据与模型计算结果进行对比验证;最后,研究海流流速、内外流流速和顶张力对深海立管涡激振动特性的影响。结果表明:海流流速越大,立管振动频率越高,振动幅值越大;立管固有频率随内流流速的增大可能降低到锁振频率范围,加速立管的疲劳破坏,顶张力对立管内流影响有明显抑制作用,立管双向耦合作用在涡激振动分析中不容忽视。

Abstract: This research is carried out in order to improve the effectiveness of predicting the VIV of deep-water risers under the collective action of multiple factors. Firstly, based on Euler-Bernoulli beam bending theory and improved Van Der Pol wake oscillator equation, the VIV predication model of marine risers was established considering the effects of internal fluid flow and cross-flow (CF) and coupled in-line (IL), a differential equation was derived by using hermit interpolation function, and Newmark-β method was used to solve the displacement of risers in time domain through iterative solution. Then a VIV experiment was conducted to verify the prediction model. Finally, the effects of sea current flow velocity, internal and external flow velocity and top tension on VIV characteristics of deep-water risers were discussed. The results show that the vibration frequency and amplitude of a riser will increase as the sea current velocity increases, the natural frequency of risers may be reduced to the range of lock frequency along with the increase of internal flow velocity, accelerating the fatigue failure of risers, and influence of internal flow is obviously suppressed by the top tension, the two-way coupling effect should be given sufficient attention in the vibration analysis of risers.

Key words: deep-water risers, vortex-induced vibration (VIV), internal fluid flowing, Euler-Bernoulli beam bending theory, wake oscillator
