摘　　要：结合工程实践,基于Schmitz理论计算出风机叶片气动外形参数并利用三维坐标变换原理计算截面翼型空间分布位置,在此基础上,以大型三维设计软件UG为工作平台建立了叶片三维气动外形,并完全满足五轴数控加工制造要求,从而验证了该方法的可靠性。这一方法简化了复杂曲面的设计过程,提高了工作效率,为后续的数控加工、模具制作、结构设计及计算奠定了基础。By combining the engineering practice and based on Schmitz Theory, the aerodynamic shape parameter of the wind tur- bine blade is calculated and the space distribution positions of blade section airfoil is calculated by using 3D coordinate conversion theo- ry. On the basis of this, the 3D aerodynamic shape of the blade is established by using the large-scale 3D design software UG as a working platform, and the five-axes CNC machining manufacturing requirements are fully met, verifying the reliability of this method. Therefore, this method has simplified the design process of complex curved surface and improved the work efficiency. And, this has laid the foundation for the following NC machining, mold making, structure design and calculation.
