【摘要】 把导管架海洋平台看作钢框架结构 ,并把多目标优化设计方法用于结构的设计中。以结构的总重量和结构构件的长细比为优化目标 ,以导管的平均直径和壁厚作为设计变量 ,考虑强度、刚度和稳定等约束条件。并以胜利油田埕北# 1 1单井采油平台为例进行了计算 ,计算结果表明此方法对海洋平台的设计具有一定的参考意义更多还原

【Abstract】 A multi objective design is proposed by assuming the jacket platform as a steel frame structure.The total weight of the structure and the slenderness ratio of the structural element are selected to be optimal objective.The average diameter and wall thickness are taken as variables in the design.Constraint conditions such as strength,stiffness,stability have been taken into account.Taking Chengbei #11 Offshore Platform as an example,the calculation results show that this proposed method is rather satisfied.更多还原
