摘要
采用叶素动量理论确定工作条件的改变对应桨距角的变化,从理论上提高桨距角的控制精度,进行了风力机变浆距机构设计。通过仿真验证了设计的正确性,同时得到了桨距角匀速转动时液压缸驱动活塞的位移、速度、加速度的变化规律。
The theory of blade element momentum is used to determine the pitch angle change under work- ing conditions, rather than empirical formula. The control accuracy was improved in theory, and based on this, pitch- regulated mechanism of wind turbine was designed. Through simulation, the correctness of the design was veryfied and the drive displacement, velocity and acceleration are achieved under the con- dition of uniform rotation pitch angle.
