摘　　要：建立大功率风电增速器行星架三维模型,计算单位静载荷作用下行星架的应力应变;依据德国劳埃德船级社规范(GL2010),给出风电增速器行星架部件的S-N曲线的拟合方法;应用Miner线性积累疲劳损伤理论和雨流循环计数法,对风电增速器行星架进行疲劳寿命分析,得到风电增速器行星架的疲劳寿命。通过对行星架疲劳寿命结果的分析,并对局部结构进行优化,为大功率风电增速器行星架的疲劳寿命分析以及设计提供参考。The 3D finite element model of planet carrier of wind turbine speed- increase gearbox is built to calculate the stress- strain of planet carrier under unit static load. The fitting method of S- N curves of the planet carrier of wind turbine speed- increase gearbox parts is given based on the Germanischer Lloyd specifications（ GL2010）. The fatigue life analysis of the planet carrier of wind turbine speed- increase gearbox is carried out by using the rain flow circulation count method and Miner linear cumulative damage theory,and the fatigue life of the planet carrier is obtained. The structure is optimized based on the fatigue analysis. The reference for the fatigue life analysis of the planet carrier and designing of large power wind turbine speed- increase gearbox is provided.
