中文摘要：
将深水抗风浪网箱的重要结构单元——浮架简化为圆环，基于流固耦合理论，建立了圆环在波浪作用下的平面外的非线性运动、变形的方程。并且利用模态叠加法进行求解，对其在实际受力情况下的运动和变形进行了数值计算。结果显示：在圆环弹性位移的前三个模态下变形较大，流固耦合效应很重要。
英文摘要：
Simplifying the floatation ring which is one of very important components of the deep-water anti-storm wave cages into a flexible ring, we obtain the nonlinear governing equations of the out-of-plane motion and deformation of a circular ring based on the fluid-structure interaction theory. The mode superposition approach is utilized to solve the equations, and the motion and deformation of the ring are numerically computed under the actual action of water waves. The computational results have shown that the deformation of the ring can not be neglected in the first three modes, and that the effect of the fluid-structure interaction is significant.
