| 摘 要： | 通过对风力机桨叶承受的载荷计算,得出桨叶绕桨叶轴转动所需的最大力矩。采用数学解析法推导出液压缸推力F是与曲柄长度r、连杆长度a、偏心距e和变桨距初装角φ四重自变量以及变桨距驱动力F1有关的函数,并利用Matlab7.1中的直接搜索工具箱得出最优值,进行优化设计。 |

| Abstract: | According to the load calculation of blade, the required maximum torque of rotational blade is obtained. A mathematic analysis method can be used to deduce the following results： the thrust of hydraulic cylinder is related to crank length, the connecting rod length, the eccentricity, the installation angle, and the variable-pitch driving force. Finally, the optimal values of pitch-controlled actuator are obtained by using the direct search toolbox of Matlab7.1 software. |
| Keywords: | wind turbine variable-pitch actuator optimal design |
