| Abstract: | The Weibull distribution and Weibull distribution are adopted to illustrate the random factors that affect gear fatigue life.Distribution parameters are estimated by using maximum likelihood,and the maximum likelihood values are obtained through optimization methods.It has been shown that the ap-proach described is simple and utilizable,and the value of parameters estimation are accurate and reason-able. |
