Zero-failure accelerated reliability demonstration test method based on degradation model

Zhang Huirui

Strategic Study of CAE 2015, Volume 17, Issue 5,   Pages 31-37

Abstract:

Traditional life demonstration test is conducted under normal conditions and fails to use degradationWe can employ degradation data to predict whether a unit will pass the test by the end of test，and theAlso higher stress can accelerate the degradation of the unit to cut down the test time.Thus it is necessary to propose a method that take advantage of both degradation data and acceleratedmodel，then the minimum sample size of different test time can be picked.
