风力机叶片主梁设计参数对帕累托前锋的影响
The influence of design parameters of wind turbine blade spar cap on prato front
摘要
Abstract
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 NSGA-II with the wind turbine blade structure design software FOUCS,and con-structing an optimization design simulation system suitable for complex wind turbine blade structures.The 15 MW wind turbine benchmark model IEA-15-240-RWT 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 self-developed 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 IEA-15-240-RWT,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.关键词
