摘要
提出了船舶结构优化设计的一般步骤,分别对双壳散货船的纵向构件、横向构件、槽形横舱壁三部分建立了结构优化设计的数学模型.采用进化算法,对“漫海”号散货船进行了实例计算,结果表明:经过优化设计,大大减轻了双壳散货船的结构重量,使之与未经优化的单壳散货船十分接近.
This paper proposes the general step of ships optimum structural design, and then separately establishes the optimum structural design mathematical model of the longitudinal, the transverse and transverse bulkhead members of the double hull bulk carrier. Finally the 'ManHai' single hull bulk carrier is calculated using the Evolutionary Computation. The result indicates that the optimization can make the weight of the double hull bulk carrier reduced to a reasonable amount in comparison with the existing single hull types, which are not optimized.
