Therefore, designing high-strength and lightweight blade structures is of great significance. In this paper, a 2MW wind turbine blade model is optimal designed by using MATLAB and UGNX software through an iterative process. The webs of the wind turbine blades are filled with honeycombs, it is found that the maximum stress of the wind turbine blades with honeycomb is significantly reduced through stress-strain analysis. Layered design is carried out on the leading edge, trailing edge, web plate, and main beam of the blade to make it closer to the actual blade application, with honeycomb layers are added. The results demonstrates that blades incorporating honeycombs exhibited higher strength and stiffness. When the blade subjects to extreme wind loads, the deflection at the tip of blades featuring negative Poisson's ratio honeycombs is only 55.60% of the regular blades. It is indicated that the application of honeycomb structures to blades can significantly mitigate the risk of blade-tower collisions, enhance durability, and prolong the lifespan of wind turbines.
