多目标优化在船型设计中的应用研究

摘要

EEDI（能效设计指数）是国际海事组织 IMO 推出的第一部专门针对海运温室气体减排的强制性法律文件，对绿色船型的研发和优化提出了更高的要求。论文提出了一种适合于概念设计阶段的多目标优化研究设计方法，并以一艘阿芙拉型油船为例，实现了该船概念设计阶段中关于主尺度连同船型的水动力性能的多目标优化，为后阶段主尺度和船型的进一步优化提供了良好基础。%EEDI (Energy Efficiency Design Index) is a CO2 emission index of ship in navigation, which is laid down by IMO and has been enforced since January 1, 2013. Enforcement of EEDI is a challenge for shipyard and design institute, and put forward higher requirements for development and optimization of green ships. On the other hand, with the ships’ development trend towards high technology, large-scale and specialization, It becomes more and more urgent to consider the mutual coupling between various disciplines in conceptual design stage. This paper provides an effective method applied in conceptual design stage, to carry out a study on multidisciplinary optimization, while an Aframax tanker is taken as an example. The given example demonstrates the practicability and superiority of the proposed multidisciplinary optimization method.
