| 摘 要： | 采用遗传算法对大型油船中剖面结构进行了基于DNV规范的优化。以舱段单位长度重量最轻为目标函数,选取了20个设计变量,从DNV规范中提取了32个关于总强度、稳定性等要求作为约束条件,并设计了相应的遗传算法数学模型。算例结果表明单位舱段长度的重量减轻了5.2%,表明该遗传算法在大型油船中剖面的结构优化方面是行之有效的。

| Abstract: | The optimization of the midship section structure of a large crude oil carrier with genetic algorithm based on DNV rules is introduced.The optimization model with 20 design variables and extract 32 constraint conditions from DNV rules about longitudinal strength and buckling strength is established.Correspondingly,the genetic algorithm model is then built for the optimum design.Results from example show that the value of objective function i.e.the weight of cargo tank sturcture per unit length decreases by 5.2% indicating a good validity of genetic algorithm in the optimization of large crude oil carrier structure. |
