具有参数漂移特征的产品可靠度分布规律研究
Reliability Distribution of Products with Parameters Digression Feature
摘要
Abstract
For the products with parameters digression feature,the reliability distribution is studied.The character and parameter estimation methods of the common distributions are analyzed,such as index distribution,normal distribution,log-arithmic normal distribution,three-parameter Weibull distribution,and Gamma distribution.For the scope of the product re-liability which obtained from the practice is different,the fitting analysis of reliability curve is studied for three kinds of situa-tion.The simulation results demonstrate if the scope of parameters can be obtained before parameter estimation the normal distribution and logarithmic normal distribution are fitting better,otherwise the three-parameter Weibull distribution is fit-ting better.关键词
