摘　　要：风力发电机组内铸件的强度分析计算,主要包括极限强度和疲劳寿命计算。铸件的极限强度计算采用有限元法进行,以轮毂为例介绍铸件的极限强度计算。铸件疲劳寿命的计算分为两个部分,即单位载荷下铸件的应力分析计算和根据铸件所承受载荷的疲劳载荷谱和单位载荷下应力值进行疲劳损伤值的雨流统计计算。The strength analysis and calculation of the wind turbine casting, include ultimate strength and fatigue life calculation. Finite element analysis method was used to calculate ultimate strength of casting. The casting hub was taken as an example to describe the ultimate strength calculation. Galculation of fatigue strength of casting was divided into two parts, namely, the stress analysis under unit load and rain flow statistical calculation for fatigue damage under fatigue load spectrum and stress value under unit load.
