【摘要】 本文在分析传统的灵敏度因子计算方法的基础上,提出一种新的灵敏度因子计算方法,它解决了传统定义中难于处理的确定性设计变量与随机变量混合和多模态失效问题分析,它不仅适合于只有随机变量和只有确定性变量的情况,也适合于它们的混合情况。接着,本文分析了影响圆柱简结构强度的各因素灵敏性问题和圆柱筒结构的可靠性灵敏性问题,本文的研究对圆柱筒结构的设计、使用具有较大的理论和实践意义。更多还原

【Abstract】 Sensitivity estimation to each of structure variables is very important during designing 、 making and using structure. In this paper, based on a new calculation method of sensitivity factors, strength and reliability sensitivity of cylinder structure is analyzed. This paper not only calculates the strength sensitivity of a cylinder structure with determinate variables, but also analyzes reliability sensitivity of the cylinder structure with random variables and determinate variables. This paper illustrates the potential for using such new method of calculating sensitivity factor in design decisions and making process on structure.更多还原
