风力发电行星齿轮传动基本构件的有限元分析

以功率为3兆瓦的风力发电增速箱为例，利用PRO／E建立行星架及齿轮等基本构件的分析简化模型，利用ANSYS软件生成齿轮啮合的三维有限元接触模型，通过对模型进行网格划分、加载和求解，求得其在额定载荷作用下的弹性变形数据。结果表明：行星架在额定载荷的作用下出现应力集中现象，应力主要集中在行星架功率输入端的传动轴部分，并且传动轴部分在载荷的作用下发生了最大位移；行星齿轮传动中各基本构件经过分析计算与校核得出其受到的最大应力均小于材料的屈服极限，符合材料的强度要求。

Finite element analysis of the basic components of the wind power planetary gear drive

Taking the power of 3 MW wind turbine growth box for example, the analysis - simple mod- el of the basic components of the carrier and gear has been established in PRO/E, and the three - di- mensional finite element contact model is generated in the ANSYS , on the premise of meshing ,load- ing and Solving of the model, obtaining the elastic deformation under rated loads data . The result shows that： stress concentration is found in the planet carrier under the rated load and is mainly in the power input shaft part of the planet carrier, and the maximum displacement is found in the drive shaft part under the role of the load, and the maximum stress of the basic planetary gear drive components by analysis calculation and checked drawn is less than the material yield limit, meeting the strength of the material.
