摘　　要：基于气动、结构一体化设计的理念,通过程序脚本驱动,由FOCUS得到叶片刚度分布。通过正交试验构建与弦长、翼型相对厚度、主梁宽度、主梁铺层层数相对应的数据库。在气动与结构计算相互迭代的过程中,根据叶片弦长、翼型相对厚度、主梁宽度、主梁铺层层数调用刚度数据库插值得到刚度。从叶片几何参数设计、刚度求解以及挥舞变形求解,实现叶片气动、结构一体化耦合设计。以5.8 MW,85 m叶片为例,限定叶片挥舞变形为16 m,求解得到的叶片符合设计需求。Based on the concept of integrated aerodynamic and structural design,the blade stiffness distribution is obtained by FOCUS driven by script.The database corresponding to chord length,relative thickness,spar cap width and plies is constructed by orthogonal test with FOCUS.In the aerodynamic and structural calculation iteration,the blade stiffness is interpolated with the database by chord length,relative thickness,spar cap width and plies.From the geometric parameter design,stiffness calculation and flap-wise deformation calculation,the integrated blade aerodynamic and structure design is realized.Taking 5.8 MW,85 m blade design for example,the blade flap-wise deformation is limited to 16 m,and the calculated blade meets the requirements.
