摘要
为了快速准确地评估产品的可靠性,通过设计高温加速寿命试验,运用均值法、卡方估计法和分布拟合法分析高温加速寿命试验产生的失效数据。对不同分析方法的结果进行对比,结果表明分布拟合法分析得到的可靠性参数接近实际结果,同时根据该方法确定的激活能以及平均故障时间模型具有可行性。
In order to quickly and accurately assess the reliability of the product,the failure data generated by the high-temperature accelerated life test are analyzed by using the mean method,chi-square estimation method and distribution fitting method.Comparing the results of different analysis methods,the results show that the reliability parameters obtained by the distribution fitting method are close to the actual results,and the activation energy and mean time to failure models determined by the method are feasible.
