摘要
基于定数截尾试验,研究恒加试验下Pareto部件的可靠性分析问题。利用经典方法和Bayes方法,给出了部件参数的极大似然估计、Bayes估计和逆矩估计。验证了极大似然估计和Bayes估计的等价性。结合加速寿命方程,推导出Pareto部件的可靠度、失效率的估计值。最后,通过仿真比较与分析,建立了Pareto部件的可靠性评估方法。
Under the type-Ⅱ censoring life test,the paper give the reliability analysis based on content-stress accelerated life test with Pareto component.MLE,Bayesian estimation and IME are given with both classical method and Bayesian method.MLE and Bayesian estimation are proved to be equivalent.Combined with accelerated life equation,the estimation of reliability function and failure rate are derived out.At last,with the help of simulation analysis,the reliability assessment method of Pareto component is established.
