摘要
涡激振动响应预报对于深水海洋结构物的设计是非常重要的。近年来，基于圆柱体的受迫振荡实验数据提出了若干经验模型。针对潘志远提出的一种基于实验数据并且与立管的有限元模态分析有机结合的VIV预报模型，采用近期的一个阶梯状分布来流下的涡激振动响应实验测量数据，验证了该模型的有效性和局限性。
The prediction of vortex-induced vibration is very important for the design of slender marine structures in deep water. Many empirical models are developed based on the data from forced oscillation tests of rigid cylindrical sections. Similar to the models, the analytic model proposed by Pan for VIV response of slender marine structures is also based on the data from tests and finite element method is integrated into this model. The capability of the model is validated by model test of riser in stepped current. And its limitation is also showed.
