摘要：
A definition of blade stiffness and a method used to calculate this definition that based on 3D shell model are proposed. Four box spars which with different layers are modeled with shell finite element and their span stiffness are calculated. The results show that local layer changing can affect blade stiffness while only affect section stiffness of a cross section. The blade stiffness proposed easy to show the overall deformation behavior of the blade. A 3D shell model of a 5MW blade is modeled and blade stiffness is calculated.(1)
