该文基于集中质量法对网衣进行了等效简化处理,在Orca Flex中建立了4?2型式的网箱群简化模型。通过改变浮圈以及浮标的密度,实现了网箱群浮于水面、浮标伴随网箱群下沉以及网箱群下沉而浮标浮于水面三种状态之间的转换,对比分析了这三种工况下锚泊系统的有效张力变化,结合网箱沉降后的变形情况给出了网箱群沉降技术的优化建议。
The cage net is simplified based on lumped mass method. With the simplification for the cage net, a cage array model composed by 4?2 cages is built using Orca Flex. The transition of three different states of the cage array is achieved by changing the density of floating buoys frame, and the dynamic response of the system in these three states is calculated. Several helpful analyses and conclusions are provided based on the results of the mooring line’s effective tension and the volume reduction of cages.
