英文摘要	Based on the zero-failure data of 30 Chinese 1.5 MW wind turbine gearboxes (WTGs), the optimal confidence limit method was developed to predict the reliability and reliability lifetime of WTG. Firstly, Bayesian method and classical probability estimation method were introduced to estimate the value interval of shape parameter considering the engineering practice. Secondly, taking this value interval into the optimal confidence limit method, the reliability and reliability lifetime of WTG could be obtained under different confidence levels. Finally, the results of optimal confidence limit method and Bayesian method were compared. And the comparison results show that the rationality of this estimated range. Meantime, the rule of confidence level selection in the optimal confidence limit method is provided, and the reliability and reliability lifetime prediction of WTG can be acquired.
