| 摘 要： | 将疲劳现象看作是存在于一个灰色系统中,运用GM(1,1)灰色预测模型对某试样的疲劳寿命进行预测,采用此方法使预测误差由原来的57.5%减小到24.2%,预测结果趋于安全,这是传统疲劳寿命计算方法所无法办到的。

| Abstract: | The fatigue phenomenon is regarded as being in a grey system.By using grey model GM(1,1)to predict fatigue life of the sample.The prediction error decreases from 57.5% to 24.2%,and the prediction result tends to be safe because the grey prediction method is adopted.This is what the traditional methods cannot do. |
| |
| Keywords: | fatigue life GM(1 1)model grey forecasting fatigue stress |
