【Abstract】 A new distribution parameters estimation method of the reliability test data of gear is presented in the paper, which combines regression analysis method and maximum likelihood functions method with optimization. The optimization estimation processfor the 3 distribution parameters of Weibull distribution is discussed by a group of concrete test data. The practice shows that this method is easy to understand and apply and the estimation value of distribution parameter is more accurate and reasonable.更多还原
