In order to reveal the influence of structural design parameters on design boundaries and improve the efficiency of wind turbine blade structure design, a structural optimization design method was proposed by combining the improved genetic algorithm NSGAII with the wind turbine blade structure design software FOUCS, and constructing an optimization design simulation system suitable for complex wind turbine blade structures. The 15 MW wind turbine benchmark model IEA15240RWT developed by NREL was chosen as the research object. The lamination, positioning, and width of the spar were treated as variables, while the blade weight and flapping stiffness were set as the optimization objectives. The selfdeveloped structural optimization design system was used to obtain the optimal solution set under different design conditions, and the influence of spar design parameters on the Pareto front was investigated. The calculation results demonstrate that for this particular blade of IEA15240RWT, a spar width of 1 000 mm, with the spar centerline positioned at 50% of the chord length, exhibits higher structural efficiency. The feasibility and effectiveness of the optimization design system for blade structure design were verified, and the system possesses strong scalability, providing new insights for more complex blade design tasks.
