摘　　要：运用概率理论和模糊集合理论,建立了产品质量等级的模糊判定和约束稳健可行域的模糊判别,将复杂的模糊概率运算又回归到常规概率计算中,建立了更符合工程实际的膜片弹簧模糊稳健优化数学模型,并以某轻型轿车单片拉式膜片弹簧离合器设计数据为例进行了计算分析和讨论。该模型可根据工程实际情况,具体设定设计方案的质量水平、合格品率或优质品率,以及设定约束水平、约束概率等关键参数。The fuzzy evaluation of product quality grade and fuzzy identification of constraint steady feasible zone were established based on probability and fuzzy sets theory,which changes the complicated fuzzy probability calculation into conventional calculation.A fuzzy steady optimized mathematic model of diaphragm spring were also established and the design data of a single-plate pull-type diaphragm spring clutch for a passenger car was taken as an example for analysis and discussion.This mathematic model can specify the key design parameters including quality level,qualified ratio or high quality ratio,as well as constrain level and constrain probability based on the actual engineering situation.
