Research on Reliability Estimation and Performance Prediction Based on Step-Up-Stress Accelerated Degradation Testing

摘要

In order to evaluate the reliability guidelines for electronic equipment with high reliability and long life quickly,this paper presents the method of step up-stress accelerated degradation testing.First expatiate step-up-stress accelerated degradation testing and the basic assumptions in detailed,then gives the data conversion method from step up stress degradation data to constant stress degradation data;At the basis,propose step up stress accelerated degradation reliability assessment arithmetic based on random degradation path;A numerical example was given to illustrate the method in the end The testing method overcomes the shortages of constant degradation testing,which has higher testing efficiency.
