Application of intelligent rain erosion system design and prediction of fatigue damage of wind power blade leading edge coating

At present, the development of wind power at home and abroad is facing many technological innovations and challenges, and the trend of large-scale blade is inevitable, but its reliability cannot be guaranteed. In view of the fact that most of the service locations of wind turbines are in areas with heavy rainfall, a set of intelligent rain erosion system is designed to simulate natural rainfall, and the life of the leading edge coating of wind turbines is predicted based on the fatigue damage of rain erosion, so as to reduce the maintenance cost of wind turbines, improve unit safety and increase energy output.
