Reliability analysisNon-probabilistic uncertaintyMultidimensional parallelepiped modelIn this paper, a new non-probabilistic reliability-based topology optimization (NRBTO) method is proposed to account for interval uncertainties considering parametric correlations. Firstly, a reliability index is defined based ...
A contrastive analysis ofnon-probabilistic reliability indexwas made theoretically and graphically between the relevant interval model and convex set model. 基于对区间非概率可靠性模型和凸集非概率可靠性模型下的非概率可靠性指标的对比分析,通过理论推导和图形分析得到两种方法下的非概率可靠性指标具有一致性,即区...
The non-probabilistic reliability problem of structures with uncertain parameters bounded by ellipsoidal convex models is investigated, and anon-probabilistic reliability modelis proposed. 构建了一种基于椭球凸集的结构非概率可靠性模型,提出了以结构安全域的体积与基本变量域的体积之比作为结构可靠性度量指标,并证...
Most of the current non-probabilistic reliability methods are applicable for an individual component of a structure. However, a system consisting of interconnected components is involved in many engineering problems and its non-probabilistic reliability analysis remains a major challenge. In this paper, ...

With the consideration of interval variables as uncertain parameters,the paper emphasizes the iterate algorithm of optimal searching path in order to get non-probabilistic reliability index.For the case of the non-linear performance function,the intersection line of the tangent plane and G=0 was achi...
Based on the interval mathematics and possibility theory, the variables existing in hydraulic turbine blade are described. Considering the multi-failure mode in turbine blade, multi-variable model is established to meet the actual situation. Thus, non-probabilistic reliability index is presented by comp...
