摘　　要：针对小型垂直轴风机的设计,采用低成本的闭模成型工艺制备了多种类型的复合材料风机叶片,通过实际运转实验验证了不同设计参数对风机运行情况的影响。结果表明,该成型工艺制作的叶片尺寸精确、质量稳定,满足平衡性要求;H叶片的启动性逊于S叶片,但具有优异的加速性能;可以通过增加叶片数目以及加大风轮旋转直径有效降低风机启动风速,并提高其转速;安装阻力型叶片可以有效改善升力型叶片的启动性能,但对风机所能达到的高额定转速影响不大;叶片安装角度的改变对风机启动及转动性能的影响随着安装角度的增大呈先提高后降低的趋势。To optimize the design of the vertical axis wind turbine,different composite turbine blades were made by low-cost closed-molding process and were tested in actual operational condition to verify the influence of different design parameters.The results show that the blades produced by this process have precise dimension,stable quality and meet the balance requirements;H-type blade has worse start-up but better acceleration property than S-type;The turbine's start-up and rotor speed property can be improved by increasing the blade numbers and rotor diameter;The drag-type blade can improve the start-up property but has no influence to the rated rotor speed;The installed angle of the blade can also affect the turbine property,and the effect is increasing at the first to decreasing finally with then angle increasing.
