摘　　要：使用非线性接触有限元方法对风力发电机主轴零件进行结构分析。模型模拟了轴承和轴套对主轴的非线性支承条件以及轴承的调心转动,给出静强度和疲劳寿命计算结果。分析结果表明,该主轴的强度、刚度和疲劳寿命满足设计要求。The strength and fatigue life of a wind turbine main shaft was computed. Nonlinear contact finite element method was used to represent support of bearing and sleeve to the shaft and to simulate the bearing＇s self-aligning behavior. The results indicate that the strength, stiffness and fatigue life of the main shaft meet design requirements, and the method is effective.
