摘　　要：采用弹性接触有限元方法对1兆瓦风力发电机增速齿轮副进行了接触仿真分析,研究了齿轮啮合计算中的相关问题。利用三维建模软件Pro/E,建立了风电齿轮增速齿轮组传动系统的实体模型,利用有限元分析软件ANSYS,得到了增速齿轮组的应力和应变规律。根据计算结果,找出了风电齿轮增速齿轮组的最危险部位,对提高风力发电齿轮传动系统的承载能力和性能有一定的指导意义。By adopting the elastic contacting finite element method, the contacting simulation of the increasing speed gear system for 1MW wind-power generation is carried out and the correlated problem in the meshing calculation is studied. Based on the software Pro/Engineer, the solid model of the increasing speed gear system for wind-power generation is built. By using the software ANSYS, the contact and bending stresses are obtained. According to the ob- tained results, the most dangerous disk position of the gear system for 1 MW wind-power generation is found. It is significant to improve the load capacity and the performance of gear transmission of wind turbine.
