一种用于变环境数据的可靠性增长分析模型

MODEL OF RELIABILITY GROWTH EVALUATING TO VARIOUS ENVIRONMENTS

提出了一种综合评估模型 ,考虑不同试验环境对产品的影响而引入环境折合系数的概念 ,从而将不同试验条件下的数据折合到相同试验条件下 ,然后利用折合后的数据再进行可靠性增长分析。最后 。

Aeronautic equipment should take a series of tests in its development phase, and its reliability is continuously improved. Therefore, The use of all these test data to evaluate the system reliability growth could effectively improve the evaluating accuracy. But first of all it should solve the varied environment problem, that is, in the test, various environments produce various data. This paper brings forward a kind of integrated reliability growth evaluation model. By using environment conversion factors the model can convert the test data from various environments into those from the same environment and afterwards analyze the system reliability improvement to make a correct evaluation. In the end, an example presents the model′s engineering practicability.
