摘　　要：采用大型有限元软件MSC.Marc/Mentat,对风力发电机组轮毂和叶片轴承螺栓联接部分进行接触分析,得到实际工况下的应力,找出了受力最大螺栓;对受力最大螺栓进行螺纹接触分析,得到了螺栓、轴承、轮毂的精确应力,有限元接触分析结果与理论计算结果吻合,材料的强度满足要求,结构安全。Using large finite element software MSC. Marc/Mentat, the contact analysis of bolted joints parts between the hub and the bearing of wind turbine is conducted for the contact stress suffering from the practical work load. The maximum stress acted on the boit is obtained, and a detail contact analysis for this bolted joints parts is given. The accurate stress of bolts, bearing and hub is calculated. The FEA contact results are consistent with the theoretical calculation results, and the strength of materials meets the requirements, which means the structure is safe.
