摘　　要：风电叶片根端连接螺栓在叶片运行过程中不断承受交变载荷作用,运用ANSYS Workbench建立有限元模型,对双头螺柱和预埋螺套进行极限工况强度校核与循环疲劳寿命验证,为风电叶片根端连接设计、优化提供可靠依据和指导。The connecting bolts at the root end of wind turbine blades are continuously subjected to alternating load during the operation of the blade.The finite element model is established by ANSYS Workbench,and the ultimate condition strength check and cycle fatigue life verification are performed on the stud and pre-embedded screw sleeve.It provides reliable basis and guidance for the design and optimization of wind turbine blade root connection.

关 键 词：高强螺栓 根端连接 应力强度 疲劳强度
