| 摘 要： | 为从有限的实验数据中获得有价值信息并减少预测误差,对某种航空材料持久强度实验数据散点图分析,用最小二乘法将实验数据拟合并检验相关性,根据拟合结果对材料给定温度下的应力值进行计算,获得应力-寿命曲线并预测结果准确度。所得结果相关性良好,应用此方法可以在较少实验数据量情况下获得材料近似持久强度特性。

| Abstract: | For getting valuable message from a small quantity of experiment data and reduce error of forecast, analyze the sporadic points figure of some kind of aero material's experiment dataof perdurable intensity, use least square method to fit data and check up correlation, according to fitting result to calculating stress value of appointed temperature, getting stress-life curve and forecast veracity of result. The correlation of result is good, using this method can get material's feature of perdurable intensity with relative a small quantity of data. |
