摘要
Abstract
An E-bayes reliability analysis method is proposed based on FTA Failure Assessment to evaluate the reli-ability of airborne equipment in case of zero-failure data.The failure rate of electro-impulse de-icing (EIDI)power supply is calculated by FTA analysis,and incorporated to the E-bayes estimation for computing the censored time for the k+1 fix-time censored test.Then the E-bayes method is used to estimate the average life of EIDI power supply.The robustness of the average life estimation of power supply is studied via a comparison of traditional E-bayes method,synthetic expec-ted-bayes method and E-bayes reliability analysis method,based on FTA failure assessment.The results indicate that this E-bayes reliability analysis method based on FTA failure assessment is robust,feasible and convenient to be applied in en-gineering in the case of zero-failure data.关键词
