针对海上浮标系泊系统,基于机理分析和力学分析得到了给定锚链型号与链长、重物球质量、海域环境(风流与海流)等系统参数下,对于声纳钢桶倾角的影响规律。在此基础上对系统各个部分进行了受力分析,并由此建立静力学平衡方程。以理论水深与实际水深的差值为优化目标,以静力学平衡方程为约束条件建立了优化模型;调节重物球,建立以重物球质量、浮标的吃水深度、游动区域半径及钢桶的倾斜角度尽可能小为优化目标,以钢桶倾角、锚链与海床的夹角要求以及静力学平衡方程为约束条件建立了多目标优化模型。在给定的实际环境参数条件下,对系泊系统进行了计算设计。
Aiming at the mooring system of offshore buoy, the law of influence on the dip angle of steel buckets under given system parameters of chain type, chain length, weight of ball, sea environment (wind current and current) was obtained based on mechanism analysis and mechanics analysis. . On this basis, the force analysis of each part of the system was carried out, and the static equilibrium equation was established. Taking the difference between the theoretical water depth and the actual water depth as the optimization objective and the static equilibrium equation as the constraint condition, the optimization model was established. The heavy ball was adjusted to establish the weight of the ball, the draft of the buoy, the radius of the swimming area and the steel barrel The objective of the optimization is to minimize the inclination angle of the bucket. The multi-objective optimization model is established with the angle of the bucket, the angle between the anchor chain and the seabed and the static equilibrium equation. Under the given actual environmental parameters, the mooring system was calculated and designed.
