摘要
深远海养殖网箱面临强流载荷下的结构失稳风险。为此,针对网箱框架屈曲、网衣流致变形及锚泊系统失效这3个力学瓶颈,提出拓扑优化强化、流固耦合仿真及阻尼节点设计等机械优化策略。通过半潜式网箱案例分析,验证抗流稳定性强化路径的有效性,为保障深海养殖装备结构安全提供技术支撑。
Deep sea aquaculture cages face the risk of structural instability under strong current loads.Therefore,this article proposes mechanical optimization strategies such as topology optimization strengthening,fluid structure coupling simulation,and damping node design to address the three mechanical bottlenecks of cage frame buckling,net clothing flow induced deformation,and anchoring system failure.By analyzing the case of a semi submersible net cage,the effectiveness of the anti current stability enhancement path is verified,providing technical support for the structural safety of deep-sea aquaculture equipment.
