Based on the principle of the cooperation, i. e, the correlative stochastic equations are located on the same probability level, the linear regression with fuzzy weight analysis is adopted to fit the test data, and the three-parameter stress-life curves o

根据协同原理，即相关联的随机方程动态地处于同一概率水准，采用模糊随机加权线性回归方法对试验数据进行拟合，得到了三参数的应力-寿命模型均值和均方差曲线，从而求得在给定应力下各可靠度的疲劳寿命。
