Abstract
The paper mainly analyzed and studied the grinding equipment for the root closing mold of 68.6 wind turbine blades. The grinding mechanism was designed and tested according to the shape, size and field working conditions of wind turbine blades. Through analysis and calculation, the straight-line walking scheme was obtained to ensure the rationality of the structure. Base on analyses of grinding theory, the grinding wheel which affects the grinding surface accuracy was analyzed. Finally, its size was determined by testing. The research and design of equipment would improve the efficiency of wind turbine blade production, and produce enormous economic and social benefits.
