考虑了板带轧机轧辊疲劳强度计算中参数的随机性和模糊性，引入了模糊事件、最大应力和最小强度的概念，在建立轧辊疲劳强度模糊可靠度预测模型的基础上，给出其模糊可靠度的计算公式，实验结果表明，该公式能使设计者更加满意，并有潜力解决轧辊的实际并行设计问题。 Considering the randomness and fuzziness of the parameters in calculating the fatigue strength of strip rolling mill rolls, the concepts of fuzzy events, maximum stress and minimum strength are introduced. Based on the fuzzy reliability prediction model of roll fatigue strength, the fuzzy reliability The experimental results show that this formula can make the designer more satisfied and have the potential to solve the actual parallel design of the roll.
