摘要
基于遗传算法采用不同的方案对缓波形钢悬链立管构型进行优化设计,优化目标分别为最小化立管静态等效应力、最小化立管动态等效应力、最大化立管疲劳寿命,设计变量为立管各段长度以及浮力材的密度,并考虑工程相关要求。通过比较分析不同优化策略的结果得到最适合缓波形钢悬链立管的优化方式,进一步为缓波形立管的设计分析提供参考。
Based on genetic algorithm,different optimization objectives are used,which are minimizing static equivalent stress,minimizing dynamic equivalent stress and maximizing fatigue life,and the design variables are the length of each section and the density of floats,while the engineering experience and related standards are considered as the constraints.By comparing and analyzing the results of different optimization strategies,the optimum method for the optimization of the lazy wave steel catenary riser is obtained,which provides a reference for the design and analysis of the lazy wave riser.
