摘要: 针对大深度水下航行器壳体结构多目标优化问题,提出一种基于自适应响应面的多目标优化方法。该方法利用实验设计得到初始点,利用响应面构造近似模型,初次优化得到Pareto解集。引入一种空间采点法,均匀得到Pareto解样点,使用高精度有限元分析技术校核后补充到初始样本集,通过一种渐近全局策略使近似模型最终满足精度。利用灰色关联分析法处理Pareto解集。结合水下航行器壳体结构实际情况,提出一种多级标度赋权法,在获得各目标权重后从Pareto解集中挑选出满意解,优化后与传统经验公式结果相比,在满足近似精度的前提下,总体性能有了一定提高。

Abstract: A multi-objective optimal method based on adaptive response surface is proposed for the multi-objective optimization of deep-sea AUV (automatic underwater vehicle) shell structure. The original samples are obtained by the experimental design, the response surface methodology is used to create an approximate model, and the Pareto solution set is obtained after optimization. A spatial sampling method is introduced to get the equally distributed samples from Pareto solution set.

Key words: system engineering methodology, shell structure, multi-objective optimization, adaptive response surface, grey relational analysis
