摘要
现今的设计问题多涉及多学科、多目标和确定性设计,忽视了系统本身的不确定性因素,设计结果通常与实际情况有很大差别。不确定性设计是设计理论发展的一个重要方向。本文综合分析了不确定性的分类、传播和设计,介绍了2种不确定性分析方法--系统不确定性分析方法和并行子系统不确定性分析方法,并对二者做了分析比较。同时指出将不确定性思想引入鱼雷总体多学科设计是鱼雷设计的发展方向。
Most current designs are multidisciplinary and multi-objective. Certainty design usually ignores the uncertainty that exists in system, which causes difference between the design and the reality. In this paper, the design and propagation of uncertainty are discussed, the system uncertainty analysis method and concurrent subspace system uncertainty analysis method are compared, and the content and method of robust design are introduced. In addition, the fuzzy of system is also considered in robust design. It is concluded that introducing uncertainty into the muhidisciplinary overall design technologies of torpedo is necessary.
