为了准确评估风力发电机行星轮系在实际工况下的疲劳寿命,以1.5 MW风机2K-H斜齿行星轮系为研究对象,通过建立精确的三维几何模型,采用HyperMesh有限元六面体网格和瞬态动力学分析,得到行星轮系啮合的应力历程及应力结构响应,并结合nCode DesignLife进行疲劳分析。结果表明,行星轮系在啮合过程中会出现偏载现象,应力集中在太阳轮与行星轮接触处;疲劳破坏集中在行星轮与齿圈接触处;齿面粗糙度在1~2 μm范围时,疲劳寿命随着粗糙度的增加而降低。
In order to accurately estimate the fatigue life of the wind power planetary gear train under actual working conditions, the 1.5 MW 2K-H helical gear planetary gear train is taken as the research object. By establishing an accurate three-dimensional geometric model, using the Hyper-Mesh finite element hexahedron mesh and transient dynamics analysis, the stress history and stress structure response of the planetary gear train meshing are obtained, and combined with nCode DesignLife for fatigue analysis. The results show that the planetary gear train will have an eccentric load during the meshing process. The stress is concentrated at the contact between the sun gear and the planetary gear. The fatigue damage is concentrated at the contact between the planetary gear and the ring gear. When the tooth surface roughness is in the range of 1~2 μm, the fatigue life decreases with the increase of the roughness.
