摘要
在符合威布尔分布的疲劳寿命数据处理中,采取通用的威布尔概率纸作图法,凭目力试凑,难以逼真地确定其分布函数的三个参数。本文按作图法顺序,将数据在计算机上应用最小二乘法拟合,可以迅速而准确地得出威布尔分布的参数值。
In processing fatique life data in accordance with WEIBULL distribution, it is difficult to use the WEIBULL probability paper and to get the best results with the naked eye so as to determine the three parameters of WEIBULL disribution. This paper, through the picture procedure, employs the least square method to draw up the data in computation in order to get the parameters both quickly and correctly.
