齿轮箱是风力涡轮机系统中最昂贵的部件之一。为了改进设计，从而提高长期的可靠性，人们越来越感兴趣的是利用时域模拟预测齿轮箱的设计载荷。在这项研究中，基于时域的齿轮接触疲劳分析在动态条件下的三个问题进行了讨论：（1）在低风速条件下的扭矩反转问题，（2）统计不确定性的影响，由于时域模拟和（3）简化长期接触疲劳分析的齿轮齿在动态条件下。基于对美国国家可再生能源实验室750 kW陆基齿轮箱可靠性协作风力涡轮机的分析，提出了解决这些问题的几点建议。
The gearbox is one of the most expensive components of the wind turbine system. In order to refine the design and hence increase the long-term reliability, there has been increasing interest in utilizing time domain simulations in the prediction of gearbox design loads. In this study, three problems in time domain based gear contact fatigue analysis under dynamic conditions are discussed: (1) the torque reversal problem under low wind speed conditions, (2) statistical uncertainty effects due to time domain simulations and (3) simplified long term contact fatigue analysis of the gear tooth under dynamic conditions. Several recommendations to deal with these issues are proposed based on analyses of the National Renewable Energy Laboratory’s 750 kW land-based Gearbox Reliability Collaborative wind turbine.
