摘要
针对某大型风电机组主轴,建立有限元分析模型,在对主轴静强度分析的基础上,根据线性累积损伤理论对其疲劳强度进行分析,并详细研究了表面粗糙度对疲劳寿命的影响。
A finite element analysis model has been established for the spindle of a large wind turbine unit. Based on the static strength analysis of the spindle,the fatigue strength has been analyzed according to the linear cumulative damage theory,and the influence of the surface roughness on the fatigue life has been studied in detail.
