提出风电叶片3D打印系统性高效制造方法。首先,采用逆向设计完成了叶片三维扫描,获取点云数据与三维模型;通过有限元方法进行静力与屈曲分析,用以结构尺寸的微调;最终,利用3D打印技术做出了实体样件模型。结果证明所提出的方法可行,且在类似风电叶片这样复杂型面构件的高效集成制造与自动化方面具有重要意义。

The systematic and efficient manufacturing approach for 3D printing wind turbine blade is proposed. First of all, with the help of the reverse design, 3D scanning of the blade is conducted, and the point cloud data and 3D model are obtained. By static and buckling analysis based on the finite element method, the detailed structure size can be fine-tuning. Finally, the entity samples are made by 3D printing technology. The results show the feasibility of the proposed approach, and prospect in efficient and integrated manufacturing and automation for building complex surfaces such as wind turbine blade.
