摘要
考虑模糊和随机因素的影响,提出广义可靠性的枚举结构静强度主要失效模式准则。此准则用模糊截集水平和置信水平定出的元件强度下限值代替原优化准则法中的强度均值,从而使得随机性和模糊性在元件强度变量中的影响得到充分的体现。
On the existed criterions to enumerate significant failure modes of the general reliability of static strength system,fuzzy effect is seldom taken into account.In this paper, a new method is presented. Because the strength mean on the optimality criterion is replaced with an inferior limit which chosen by the λcut level and confidence level, both fuzziness and randomness are considered compeletly in the determination of criterion elements. Finally, an example is given to show the availability of the new one.
