摘要: 建立了雨滴冲击叶片涂层前缘的模型,通过动力学软件研究雨水冲击涂层过程中的受力状况,并通过实验证明了这种观点,然后对涂层材料的优化组合提出建议,最后研究了雨蚀过程中叶片表面水膜对雨滴冲击的缓冲效应。结果表明:雨滴的冲击会造成涂层的拉伸疲劳破坏,在涂层的优化组合时选用模量较低的漆料放置于表层可以减小涂层所受的拉伸应力,涂层表面水膜能够明显减少冲击时的应力。

Abstract: The model of raindrop impact blade coating leading edge is established. The dynamics software is used to study the stress state of rainwater impact coating process. The viewpoint is proved by experiments, and then the optimal combination of coating materials is proposed. Finally, the buffering effect of water film on the surface of raindrops on raindrop impact during rain erosion is studied. The results show that the impact of raindrops will cause tensile fatigue damage of the coating. In the optimized combination of coatings, the paint with lower modulus is placed on the surface layer to reduce the tensile stress on the coating. The water film can significantly reduce the stress of the coating when it is impacted.

Key words: wind power blade, coating, impact failure, erosion
