基于多目标规划的系泊系统的设计

Design of Mooring System Based on Multi-objective Pprogramming

论文应用多目标规划的数学方法以及静力学原理等物理知识,设计新的系泊系统,使其能尽可能地适应环境条件.首先对系泊系统海上漂浮部分进行受力分析,得出了钢桶的倾斜角度、浮标的活动半径、浮标的吃水深度3个变量随重物球质量变化的关系,建立以吃水深度、活动半径,钢桶倾角为目标函数的多目标优化模型,并确定了最佳锚链型号、长度、重物球质量及相应的钢桶和钢管与竖直面的夹角、锚链形状、浮标的吃水深度和游动半径,并由此判断出所设计的系统是否合理有效.

Based on the multi - objective programming and the principle of static mechanics, this paper designs a new mooring system so that it can adapt to the new environmental conditions as much as possi- ble. Based on the force analysis of the floating part of the mooring system, we obtained the relationship a- mong the inclination angle of the steel bucket, the movable radius of the buoy and the draft of the buoy to the change of the ball quality.Taking the draft depth, activity radius and the inclination angle of the steel bucket as the objective function,the optimal anchor chain type,length,ball quality and the corresponding steel bucket and the angle between the steel bucket and the vertical plane are determined,the chain shape, the buoy draft depth and activity radius are also involved, and by which determines whether the design of the system is reasonable and effective.
