摘要: 基于潜艇操纵性评判的研究, 通过对低速变质量水下航行器特征的分析, 提出了一种低速变质量水下航行器操纵性评价方法——多级模糊综合评判。选取对低速变质量水下航行器操纵性影响显著的性能指标建立了评价因素集, 采用岭型分布隶属度函数计算了评判因素集评判矩阵, 运用模糊层次法确定了各评价因素集的权重集, 通过模糊运算得到了操纵性模糊评判结果。多级模糊综合评判可对低速变质量水下航行器的操纵性进行定量分析, 计算结果可靠性高, 可为工程应用提供参考。

Abstract: A maneuverability evaluation method of low speed variant mass underwater vehicle, named multi-level fuzzy comprehensive evaluation, is proposed based on the evaluation of submarine maneuverability and the characteristic analysis of low speed variant mass underwater vehicle. Evaluation factor sets are established by selecting the performance indexes with significant effects on the low speed variant mass underwater vehicle, the matrix of the evaluation factor sets are calculated via the membership function with ridge-shape distribution, and the weight sets of the evaluation factor sets are determined by using fuzzy analytical hierarchy process to obtain the fuzzy evaluation results of maneuverability. The proposed multi-level fuzzy comprehensive evaluation method can be used for quantitative analysis on maneuverability of low speed variant mass underwater vehicle, and the analysis results are reliable for engineer application. -
