基于目标驱动优化的海洋浮标平台系泊方案设计

Mooring Scheme Design of Ocean Buoy Platform Based on Target Driven Optimization

海洋浮台系泊性能,对平台安全及仪器设备的可靠性具有重要影响。论文着眼于优化浮台系泊性能,从目标驱动优化角度对现有的缆索方案进行优化设计。通过响应面力学分析,研究在满足浮台摇动角度的谷值与峰值以及缆索张力的峰值最小的情况下,缆索的轻量化设计。在五级海况下将初始方案与优化方案进行了对比,结果证明优化设计有效减轻了缆索的重量,减小了浮台的摇动与缆索的张力。为缆索在满足的强度要求下的轻量化设计提供了解决方案。

Mooring performance of offshore floating platform has an important impact on platform safety and reliability of instruments and equipment. This paper focuses on optimizing the mooring performance of floating platform,and optimizes the existing cable schemes from the perspective of target-driven optimization. Through response surface mechanics analysis,the lightweight design of cables is studied under the condition that the valley and peak values of the shaking angle of the floating platform and the peak values of cable tension are minimum. The results show that the optimal design can effectively reduce the weight of the cable and the shaking of the platform and the tension of the cable. It provides a solution for the lightweight design of cables under the strength requirements.
