以1.5 MW风电齿轮箱齿轮为研究对象，基于齿轮的设计参数，通过机械零部件动态可靠性模型，得到风电齿轮箱齿轮的寿命分布模型。假设它的寿命分布函数分别服从双参数威布尔分布和对数正态分布，并用最小二乘法对两种分布形式的参数进行估计，用相关系数法对两种分布形式的估计结果进行检验。检验结果表明，两种分布形式中威布尔分布对寿命分布模型的分布函数形式拟合得较好，由此确定的寿命分布函数对于零件全生命周期的管理具有一定的指导意义。

An 1.5 MW wind turbine gearbox is considered as the research object in this paper. The life distribution model of the turbine gearbox is obtained by building dynamic reliability models of mechanical components based on design parameters. The life distributions are assumed to follow Weibull distribution with two parameters and lognormal distribution, and the parameters estimation is conducted with the least square method. The correlation coefficient method is then used to testify the estimation results. The results show that the Weibull distribution fits the life data well.
