| 摘 要： | 通过离散涡方法求解立管所受涡激升力,并与立管动力响应方程相耦合来对涡激振动问题进行时域内的数值模拟。通过在均匀来流和剪切来流下的模拟,所得的结论与其他文献中的结论比较吻合,较好地揭示了立管涡激振动的特征。

| Abstract: | Discrete vortex method is used to calculate the lifting force induced by the vortex shedding from the structure. The results will couple with the riser dynamic response equation to realize a numerical simulation of VIV in time domain. Some conclusions are got after simulating the VIV phenomenon of riser under uniform flow and shear flow, then they compared with other literatures＂ conclusions show a good agreement, and the VIV characteristics of riser are revealed better. |
