Detection of Faults in Planetary Gearboxes in Wind Turbines

变速箱是风力涡轮机最昂贵的部件之一。然而，与整个风力涡轮机的寿命相比，变速箱的平均寿命要短得多。因此，本项目旨在开发理论来解释风力发电机变速箱的故障模式，以及如何设计变速箱以更好地处理这些故障模式。这将包括研究检测变速箱出现故障的方法，开发分析模型来模拟变速箱的动态行为，并进行实验测试以支持所开发的理论。

The gearbox is one of the most expensive components of a wind turbine. However, the average lifetime of a gearbox is considerably shorter in comparison to the lifetime of the overall wind turbine. Therefore, this project aims to develop the theory for explaining the modes by which wind turbine gearboxes fail, and how to design gearboxes to better deal with these modes of failure. This will include investigating the means of detecting the onset of faults in the gearbox, the development of analytical models to simulate the dynamic behaviour of the gearbox, and experimental testing to support the developed theory.
