高可靠性产品退化建模研究综述

Review of Degradation Model for High Reliability Products

退化建模是解决高可靠性、长寿命产品可靠性评估及贮存寿命预计问题的一种新策略。从基于物理失效的退化模型和基于统计的退化模型两个方面对高可靠性产品退化建模的发展现状进行了综述,概括了两类模型涉及的失效机理、建模、试验配置、模型误判等,并对常见的两类模型进行了介绍。论文还阐述了退化模型与寿命估计的关联关系。

Degradation modeling is a new strategy for dealing with the reliability assessment and storage life prediction of products with high reliability and long life.The development status of degradation modeling,including degradation modeling based on failure mechanisms and degradation modeling based on statistical,of products with high reliability are reviewed in this paper.The failure mechanism,modeling,test configuration,mis -specification of models about those two models are summarized.Then the typical models are introduced and the relationship of degradation model and the lifetime estimation is described.
