摘要

直驱式风力发电机组中的支承轴是风力发电机组的重要支承部件，其性能直接影响到风力发电机组的安全运行。本文结合直驱式风力机支撑轴的特点，结合有限元法和工程方法，对支撑轴进行了静、模态疲劳寿命有限元分析。通过对支撑轴进行静力分析，变形和应力应变结果表明，最大应力小于许用应力，支撑轴满足静强度安全要求;通过疲劳寿命分析，最大疲劳应力低于理论疲劳极限，满足支撑轴的疲劳强度要求。研究结果为改进设计和方案定稿提供了理论依据。

The strength analysis of the Direct Drive Wind Turbine's support shaft

The support shaft in the Direct Drive Wind Turbine is an important supporting component of the wind turbine and its performance directly affects the safety of turbine. Through combining characteristics of the Direct Drive Wind Turbine's support shaft with finite element method and engineering method, this paper analyzes the support shaft finite element of static and modal fatigue life. Through the static analysis of the support shaft, the deformation and stress-strain results show that the maximum stress is lower than the allowable stress, and the support shaft meets the static strength safety requirements; through fatigue life analysis, the maximum fatigue stress is lower than the theoretical fatigue limit and meets the fatigue strength requirements of the support shaft. The results provide a theoretical basis of improvement of the design and program finalization.
