Abstract：[Objective]In view of the current limitation that the structural optimization of wind turbine blades mainly focuses on size or layup while the internal configuration is relatively fixed,through the topology optimization to seek the optimal material layout for the blade web,achieve lightweight design of the blade and explore structural innovation.[Methods]Firstly,the topology optimization module of Abaqus software was adopted to establish the web structure optimization model.Secondly,with the maximization of structural stiffness as the objective function,the material distribution was optimized under the premise of meeting volume constraints.Finally,a comprehensive comparative analysis was conducted on the mass distribution,stiffness distribution,vibration resistance performance and buckling performance of the optimized new web structure.[Results]The results show that the mass of the web plate is reduced by approximately 4.56%after optimization.The topology optimization of the blade web does not significantly affect the overall mass and stiffness distribution,maintaining good vibration resistance.Although the maximum stress of the web plate has increased and the buckling factor has slightly decreased due to the weakened support,they are all within the allowable range and safety range of the material,verifying the topological optimization effectiveness in the lightweight design of blades.
