【摘要】 本文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。更多还原

【Abstract】 The weight of large crude oil carrier midship section structure is minimized with genetic algorithm based on DNV rules. The optimization model is built, which have 20 design variables and extract 32 constraint conditions on longitudinal strength and buckling strength, etc. from DNV rules. Corresponding GA model is built for the optimum design. Results of example show that the value of objective function decreases by 5.2%, indicating good validity of GA for large crude oil carrier structure optimization.更多还原
