本文将结构系统可靠性分析方法与损伤容限设计要求相结合,以飞机结构中常用的加筋板结构加以模型化为例,作了方法上的阐明;把常规的损伤容限设计,提高到以损伤容限设计为要求,计算其可靠性。有关损伤容限设汁方面的计算公式取自文献[1],结构系统可靠性分析方法则可参考文献[2～3]。 In this paper, the reliability analysis method of structural system is combined with the requirement of damage tolerance design, taking the modeling of stiffened plate commonly used in aircraft structure as an example, the method is clarified. The conventional damage tolerance design is improved to To damage tolerance design requirements, calculate its reliability. The formulas for calculating the damage allowance are taken from the literature [1], and the reliability analysis of structural systems can be found in references [2 ~ 3].
