目的
2
针对目前风力机叶片结构优化多集中于尺寸或铺层而内部构型相对固定的局限性,通过拓扑优化寻求叶片腹板的最优材料布局,实现叶片的轻量化设计并探索结构创新。
方法
2
首先,基于Abaqus软件拓扑优化模块,建立了叶片腹板的拓扑优化模型;其次,以结构刚度最大化为目标函数,在满足体积约束的前提下优化了材料分布;最后,对优化后的新型腹板结构进行了质量分布、刚度分布、抗振性能以及屈曲性能的综合对比分析。
结果
2
结果表明,优化后的腹板质量降低约4.56%;新型构型在保持叶片整体质量与刚度分布基本不变的同时,具有良好的抗振性能。尽管腹板最大应力有所增大且屈曲因子因支撑减弱而略有降低,但均处于材料允许范围及安全区间内,验证了拓扑优化在叶片轻量化设计中的有效性。
Objective
2
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
2
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
2
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.
