本文应用已有的研究成果，建立了一个表面疲劳分析模型，用于预测降雨对风力涡轮机叶片涂层前缘的侵蚀。我们使用雨蚀旋臂试验来确定现场使用的不同涂层的表面抗冲击疲劳性。分析模型已经过验证，可以通过使用从多个国家、海上和陆上风电场拍摄的前缘侵蚀观测照片的大型数据库来预测风力涡轮机前缘侵蚀的开始。还对侵蚀的空气动力学影响进行了建模，并用于确定受损翼型的预期截面效率损失。将前缘侵蚀预测模型与效率降低模型相结合，我们可以预测由于雨致风力涡轮机叶片涂层前缘侵蚀而导致的不同地点的年能量生产损失。
This paper applies existing research to develop an analytical surface fatigue model to predict the initiation of leading edge erosion on wind turbine blade coatings due to rainfall. We have used rain erosion whirling arm tests to determine the surface impact fatigue resistance of different coatings used in the field. The analytic model has been validated to predict the initiation of wind turbine leading edge erosion by using a large data base of photos of leading edge erosion observations taken from wind farms in multiple countries, offshore, and onshore. The aerodynamic impact of the erosion has also been modeled and been used to determine the expected sectional efficiency loss of the damaged airfoils. Combining the leading edge erosion forecast model with the efficiency reduction model, we can predict annual energy production loss over time on different sites due to rain-induced wind turbine blade coating leading edge erosion.
