摘要
介绍了材料疲劳试验数据中可疑观测值的判断原理,并设计了一种用于计算材料试验数据中可疑观测值的软件。该软件使用Visual C#语言编写,可以从试验数据中挑选出可疑观测值,并能计算出平均值和标准差等数据,计算完成后输出显示可疑观测值及其在数据组中的具体位置,最后用实际测试数据对软件的功能和计算准确性进行了验证。结果表明:该软件计算结果准确,使用方便、灵活,提高了材料疲劳试验数据的处理效率;该软件也可用于材料其他试验数据中可疑观测值的计算。
The judgment principle for doubtful values in material fatigue test data was described and the application software was developed for doubtful value calculation. Development language was Visual C#. The software could be gotten doubtful values, average values and standard deviation and so on. The doubtful values should be located in the sample and showed. The software functions and calculation accuracy had been verified via the actual test data. The results showed that the software was conveniences and flexible, and improved the efficiency for dealing with material fatigue test data, and also could be used to deal with other test data.
