基于退化量分布的可靠性建模方法
Reliability Modeling Method Based on Degradation Data Distribution
摘要
Abstract
Reliability modeling method based on degradation amount distribution offers an effective approach for reliability assessment of long-life and highly reliable products, especially in the situation that the degradation paths among product individuals are obviously different. To improve the dependability of assumptions on the degradation amount distribution type and parameters of distribution, the method, by which the degradation amount distribution type was selected by good-ness-of-fit test and the parameters of distribution are determined by data fitting, was proposed. Taking the crack degrada-tion data of some type metal product as an example, the application procedure of the proposed method was detailed demon-strated. Resluts suggested that the proposed method provided high accuracy and reliability.关键词
