基于多目标优化算法的系泊系统设计

Mooring System Design based on Multi Objective Optimization Algorithm

系泊系统设计对近浅海观测网的信息传输起到了至关重要的作用.针对存在风力和水流力的多成分系泊系统,建立了计算锚链形状、钢桶和钢管的倾斜角度、浮标的吃水深度和游动区域为主的多参数多目标优化模型.结合力与力矩的平衡方程,分析了各参数的约束条件.以吃水深度、最大游动距离和钢桶倾角作为目标函数,并根据多目标遗传算法求解得到最优设计方案.最后通过模型检验,验证了方案的可行性.

The design of mooring system plays an important role in the information trans- mission of the observation network in the near sea. Given a mooring system environment for the presence of wind and water, the force analysis of each component in the space coordinate system is established. Combine the balance equation of force and moment, analyse the con- straint conditions of each parameter, and construct the water depth, the maximum swimming distance and angle steel as the objective function variables. Finally, the optimal design scheme is obtained according to the multi objective genetic algorithm, and verify the feasibility of this scheme.
