摘　　要：文中研究目的是开发一种使垂直轴风力机自启动能力强、风能利用率高的随动变桨技术,此变桨技术的原理是在不需添加任何外加动力的情况下,利用风力机主轴旋转的同时带动风力机叶片的旋转,且保持主轴的旋转角速度是叶片旋转角速度的2倍。通过运用数值模拟的方法,得到了该新型随动变桨垂直轴风力机的气动参数值及特点;并分别将其与传统垂直轴风力机、理想直叶片垂直轴风力机的气动参数进行了对比分析,分析结果表明:新型随动变桨垂直轴风力机的气动性能优于其它两种类型风力机。In this paper, a servo pitch technology has been studied and developed which can improve self - starting ability and wind energy utilization of vertical axis wind turbine. The technology does not need to add any external devices, just to use the rotation of wind turbine spindle to drive the rotation of wind turbine blades directly, and keeps the rotating angular velocity of spindle being twice as much as blades. The aerodynamic performance of a new type of servo variable blade vertical axis wind turbine is analyzed by numerical simulation, and the pneumatic parameter value and characteristics of the wind turbines are get. In addition, the pneumatic parameter value of the new type wind turbine is compared and analyzed with traditional vertical axis wind turbine and straight blade vertical axis wind turbine under the ideal state, and the results show that the aerodynamic performance of new servo variable blade vertical axis wind turbine is better than the other two types of wind turbine.
