摘　　要：应用有限元法对某兆瓦级风力发电机组主机架进行极限强度分析.基于GL规范分析风力发电机组主机架疲劳计算需要考虑的载荷工况,并对主机架进行疲劳寿命分析.对计算结果进行校核评价,指出主机架结构易发生疲劳破坏的部位.分析结果可为兆瓦级风力发电机组主机架的结构设计提供参考.The finite element method is used to analyze the ultimate strength of the mainframe of a megawatt wind turbine set. According to the GL standard, the load conditions for the fatigue calculation on the mainframe of wind turbine set is analyzed, and the fatigue life of the mainframe is analyzed. The calculation results are checked and evaluated and the dangerous fatigue parts of the mainframe structure are indicated. The analysis results can provide reference for the design of the mainframe of megawatt wind turbine set.
