中文摘要	鉴于非耐压承载结构对于U U V(U nm anned U nderw ater V ehicle)的重要意义,提出一种基于折衷规划法建立综合目标函数,以灰色—层次分析确定子目标权重系数的多目标优化方法。以某型U U V的非耐压承载结构为例,首先采用灰色—层次分析法,得到各子目标(典型工况的柔度和前三阶固有频率的平均值)的权重系数;然后,采用折衷规划法进行多目标拓扑优化设计。优化结果表明:该方法适用于U U V非耐压承载结构的初始设计,可行且有效。同时,对比层次分析法和灰色关联分析法,该方法计算效率更高,优化结果更加合理。
英文摘要	In view of the importance of non-pressure-bearing structure to UUV, a multi-objective optimization was presented based on the compromise programming method to establish a comprehensive objective function, with the grey-analytic hierarchy process to determine the weight factors of the sub objective in this paper. Taking the non-pressure-bearing structure of UUV for example, firstly, the weight factors of the sub objective (the flexibility of the typical operating conditions and the average value of the first three order natural frequencies) was obtained with the grey-analytic hierarchy process according to the optimization results. Then, the multi-objective topology optimization design was carried out with the compromise programming method. The optimization results show that the method presented in this paper is feasible and effective for the initial design of the UUV non-pressure-bearing structure. At the same time, the method of grey-analytic hierarchy process is more efficient and more reasonable than analytic hierarchy process and grey relational analysis.
