摘　　要：通过限制叶片的变形范围,以发电量最大为目标函数,使叶片在轻量化以及刚性方面取得平衡,并通过粒子群优化算法,全局进行寻优。以5.8 MW,85 m叶片为例,通过查表插值求得叶片各截面刚度分布,并采用二结点梁单元分段进行叶片挥舞方向的变形,在变形约束内,求得发电量最高所对应的叶片几何参数。By limiting the deformation range of the blade and setting the maximum power generation as the objective function,the blade performances can be balanced in terms of lightweight and rigidity.The particle swarm optimization algorithm is used for whole optimization.Taking the 5.8MW,85m blade as an example,the stiffness distribution in each section of the blade is obtained by interpolation from the database,and the two node beam element is used to calculate the deformation.Within the deformation constraints,the blade geometry corresponding to the highest power generation is obtained.
