摘　　要：风力发电机叶片形状直接影响风力发电机气动性能,根据风力发电机叶片特点规划测量路径,采用三坐标测量机(CMM)对风力发电机叶片表面进行测量,提取表面的三维点云数据。对点云数据进行分组和处理,在Pro/E中生成叶片的三维几何模型。在Fluent软件中对叶片翼型进行了不同攻角的气动特性分析,得到了不同攻角下的流场分布情况。The blade shape of wind turbine is the cureial influence factor on the aerodynamic performatnce of wind turbine. According to the characteristics of the wind turbine bladw disign planning measurement path and the point cloud data of 3D geometrical surfaces of wind turbile bladw were obtained through measuring with a three-Coordinate Measruin Machine （CMM）. The point ehiud data were processed and grouped. The 3D geometrieal model of wind turbine Made was reconstrueted by using a software of Pro/E, Aerodynamic eharacterislies of different allgles of＇ altack of the hlade were analyzed in Fluent software, diferent angles of attack of the flow field distribution was ohtaitled.
