摘要

细长结构物在海洋来流作用下会发生涡激振动(vortex-induced vibration，VIV)，涡激振动是海洋立管疲劳损伤的主要诱因之一。立管实际工作过程中内部输送油气，产生惯性力、科氏力（Coriolis力）和离心力，使得立管的动力响应变得更为复杂。基于含内流立管涡激振动响应时域预报模型，分别计算了在均匀流和剪切流下含内流立管涡激振动响应，并分析了机理较为复杂的科氏力作用。结果表明：均匀外流下内流会降低立管的固有频率，增大响应幅值；剪切外流下内流会激发出更高阶的模态响应。均匀外流下，科氏力在一定区域内固定做正功或负功，分别引起均方根位移的增大或减小；剪切外流下，科氏力使得立管顶部区域均方根位移升高，中部区域均方根位移降低。内流速度越大，科氏力效应越显著。

Abstract

Vortex-induced vibration (VIV) occurs in slender structures under the action of ocean currents, which is one of the main causes of fatigue damage of marine risers. The riser is filled with oil and gas during operation, and the internal flow will generate inertial force, Coriolis force and centrifugal force, which makes the dynamic response of the riser more complicated. Based on a time-domain prediction model of VIV response of the riser with internal flow, VIV response of the riser with internal flow under uniform and shear currents are calculated. The Coriolis force with complicated mechanism is analyzed. Internal flow reduces natural frequencies and increases VIV amplitude of the riser under uniform current, and it triggers higher modal order response under shear current. Under uniform current, Coriolis force does positive or negative work in a certain area, causing the root-mean-square (RMS) displacement to increase or decrease respectively. Under shear current, Coriolis force increases the RMS displacement in the top area of the riser, and decreases the RMS displacement in the middle area. The larger the internal flow velocity is, the more significant the Coriolis force effect is.
