【摘要】 讨论了以强度为离散模糊变量、应力为离散随机变量时,通过把模糊变量向随机变量变换,进行模糊可靠性分析的方法,并把分析结果与以前的模糊可靠性分析结果进行了比较,验证了方法的可行性,为模糊可靠性分析方法的研究提供了新的思路。该方法同样适用于以应力为离散模糊变量、强度为随机变量的情况,或应力和强度均为离散模糊变量的情况。更多还原

【Abstract】 For the first time, this paper put forward an approach for fuzzy reliability analysis by means of the transformation from a discrete fuzzy strength to a discrete random strength when the strength was a discrete fuzzy variable and the stress was a discrete random variable, and compared the results obtained from the approach in the paper with the results obtained from the approach before. Therefore, the paper gives a new idea to analyze fuzzy reliability, and the approach in the paper holds true in the reliability analysis when the stress is a discrete fuzzy variable and the strength is a discrete random variable, or both stress and strength are discrete fuzzy variables.更多还原
