极限海况下浮标运动及锚链受力估算

Estimation of Buoy Motions and Chain Forces in Extreme Sea State

本文首先利用三维势流理论计算了自由浮标体的附加质量、阻尼系数以及运动响应,然后通过卡明斯六自由度运动方程,对极限海况下两个水深的三锚系统的浮标运动及锚链受力进行了数值模拟估算,可以为浮标及锚链设计提供参考。

Firstly, the added-mass, damping coefficients and motion responses of a buoy were calculated by the three-dimensional potential theory. And then the motions of the buoy and the forces of the chain for both water depths under the extreme sea state were simulated in the time domain in terms of the Cummins' equations of six-degree. It is useful for the design of the buoy and the mooring chains.
