摘　　要：详细分析了主轴及胀紧联结套的受力情况,建立了风力发电机主轴模型,分别应用工程计算和有限元分析方法,对主轴在极限工况下进行了强度分析,有限元分析时结合工程计算考虑了胀紧联结套对主轴的作用,对两种方法结果进行了对比分析,指出工程计算方法的局限性,提出有限元分析更为准确,为风力发电机主轴的结构强度分析提供了一个更为准确的分析思路,具有一定的工程实用意义。The shaft and spindle sleeve coupling stress condition was analyzed,and the wind turbine shaft model was established.Applying elasticity theory and finite element theory respectively,the strength analysis of the wind turbine shaft under the condition of limit load was conducted.While the finite element analysis with engineering calculations,it took into account the swelling of the spindle sleeve coupling effect.Comparing the two results,the limitation of engineering calculation was pointed out.On the contrary,the finite element method obtained a more accurate result,and presented a more precise idea of the strength analysis of the wind turbine shaft.The project has a practical significance in engineering.
