摘要
利用可靠性和模糊集理论建立了磨损的模糊可靠性设计公式,并推导出磨损量服从正态分布,模糊分布为降半矩形,降半梯形及降半正态分布时的模糊可靠度计算公式。给出了计算实例,这种方法可以推广到类似的可靠性设计中。
Reliability and fuzzy sets theories are used to establish a for-mula of fuzzy reliability design on wear evaluation. Also, the calculating for-mula for fuzzy reliability are given subject to that the wear-off variable obeysnormal distribution and its fuzzy distribution shows descending semi-rectangl,semi-trapezoid or semi-normal. An evaluation instance is included and themethod shows available to extend to other reliability designs similar to that.
