摘　　要：轻便的风力机可以在野外环境下满足人们活动和生存的电源需求。文章针对便携可折叠需求,提出了一种便携折叠式H型垂直轴风力机。对风力机风轮参数和折叠机构进行了设计,采用双致动盘多流管模型对比分析了采用不同翼型的叶片气动性能,确定较优翼型。运用双致动盘多流管模型算法计算叶片的极限载荷,求解采用不同材料时叶片的重量,寻求适合便携式风力机叶片的材料。对极限载荷作用下的折叠机构连接杆进行静力学分析,保证风力机结构的设计安全性。静力学分析结果表明:采用NACA0018翼型的叶片气动性能更优;材料选择PEEK ST45CA30时,叶片重量最轻;在极限载荷作用下,设计的折叠机构连接杆满足安全要求。The portable wind turbine can meet the need of power for human activities in the wild environment.According to the portable and foldable requirements,a portable folding H-type vertical axis wind turbine is proposed in this paper.Rotor parameters and the folding mechanism are designed,and the aerodynamic performance of blades with different airfoils is compared and analysed by using the double-actuated disc multi-flow tube model so as to determine the better airfoil.The weight of blades of different materials is obtained on the basis of the ultimate load of the blades calculated by the double actuating disc multi-flow tube model,and then the blade materials for portable wind turbine can be determined.The structural safety is guaranteed by static analysis of the connecting rod of folding mechanism under the ultimate load condition.The results show that the aerodynamic performance of the blade with NACA0018 airfoil is better,and the blade made of PEEK ST45 CA30 is the lightest,and the safety requirement of the folding mechanism is met under the ultimate load condition.
