摘要

为了研究水产养殖网箱的水动力性能，基于势流理论和Morrison方程建立了网箱的水动力模型，并对网箱的运动响应幅值算子(RAO)进行了分析。基于准静态方法，分别设计了全链系泊系统和三段系泊系统。计算了风、浪、流共同作用下网箱的运动响应，并对两种系泊方案进行了比较。研究表明，在50年极端环境载荷下，三段系泊方案可以有效降低系泊线的最大张力，减轻系泊线的自重。

Hydrodynamic analysis and design of mooring system for an aquaculture fish cage

In order to study the hydrodynamic performance of an aquaculture fish cage, the hydrodynamic model of the cage was established based on the potential flow theory and Morrison equation, and the motion response amplitude operator (RAO) of the cage was analyzed. Based on the quasi-static method, the full chain and three-segment mooring systems are designed respectively. The motion response of the cage under the combined action of wind, wave, and current was calculated and the two mooring schemes were compared. This study shows that the three-segment mooring scheme can effectively reduce the maximum tension of the mooring line and reduce the weight of the mooring line under 50-year extreme environmental loads.
