摘　　要：针对风机叶轮过载失效的情况,计算风机叶轮的载荷。利用三维软件建立叶轮三维模型,详细介绍三维湍流风模型的建立过程,仿真得到3种不同风速的湍流风模型下叶轮所受载荷,并对其进行分析,为风力发电机组主要零部件的优化设计提供参考。The loads of the rotor were calculated by aiming at the cases of rotor failure caused by over load. The 3D rotor model was built by 3D software, and the process was described that the 3D turbulent wind model was built. Accordingly the loads of the rotor were calculated under the 3D turbulent wind model with three different wind speeds and they were analyzed. It provides references for the other main parts＇ design and optimization.
