摘要
提出用灰色系统理论中的GM(1,1)模型对金属材料的疲劳寿命试验数据进行预测 ,目的是大幅度缩短试验时间 ,节约试验费用 ,快速获得可靠性指标。实例计算结果说明 ,将灰色系统理论用于金属材料的疲劳寿命试验数据预测有较高的精度 。
The GM (1,1) model in the grey system theory was proposed to predict the test data of fatigue life of metal materials,the aim was to largely cut short test time,save test cost,quickly obtain reliable index. The calculation result shows that a higher accuracy could be obtained by applying the grey system theory to prediction of the test data of fatigue life of metal materials,and a valuable method was proposed for shortening the test time of fatigue life of metal materials.
