应用环境应力分类的加速贮存退化试验评估方法

摘要

目的：解决加速试验在估计产品贮存寿命中误差较大、未考虑结合实际贮存中的退化信息等问题。方法基于加速退化试验中广泛接受的基本假设，并将其应用到实际贮存中，把加速试验与实际贮存中的信息综合起来进行处理。结果得出了一种使用实际贮存信息修正试验预计结果、估计剩余寿命的方法。结论应用该方法在贮存过程中只需对少量性能参数进行测量，即可估计产品的剩余寿命。%Objective To solve the problems of the relatively large error of accelerated test in estimating the product storage life, and not considering the actual storage degradation information. Methods The widely accepted basic assump-tions of accelerated degradation test was applied in actual storage, and the information from both actual storage and acceler-ated degradation test was brought together for analysis. Results A new method which could amend the test results by actual storage degradation information and estimate the remaining life was obtained. Conclusion By using this method, we could estimate the remaining life in actual storage only after measuring several performance parameters.
