| 摘 要： | 为了解决产品中突发型失效与退化型失效共存的竞争失效下可靠性评估,本文在确定产品性能退化量分布模型的基础上,给出了突发型与退化型失效的竞争失效的一般模型,该模型考虑了突发失效率与退化量的相关性.通过分析金属化膜脉冲电容器的退化失效机理,利用该竞争失效模型,对金属化膜脉冲电容器进行了可靠性分析,确定了该型电容器的可靠度函数...

| Abstract: | The competing risk problems involving both traumatic and degradation failures are modeled for the reliability evaluation at competing risk involving multiple failures.The degradation level dependence of traumatic failure rate is included into the model.The competing failure model is used to analyze the reliability of metallized-film pulse capacitor by researching the degradation mechanism of metallized-film capacitor. |

| Keywords: | reliability evaluation degradation failure competing failure metallized-film capacitor |
