摘　　要：随着风电产业的发展,风电叶片已由原来的kW级发展到现在的6MW级,甚至更大。风电叶片模具一直采用玻璃钢复合材料,成型工艺采用真空灌注成型。模具长度由最初的10m发展到现在的60m,甚至更长,其型面精度变得愈加难以控制。风力发电的效率高低直接取决于叶片翼形的准确,这就需要叶片模具的型面尺寸与设计值具有较高的吻合度。因此,本文开展了大型风电叶片模具型面精度控制等相关研究。With the development of wind power industry, wind turbine blade had been developed from the origi- nal kW to the latest 6MW or more. Wind turbine blade mold was manufactured from composite material with vacuum infusion molding process. The mold length was from the initial 10m to 60m or longer, and the surface accuracy be- came more and more difficult to control. The efficiency of wind power depended directly on the accuracy of blade wing. So high accuracy of mold surface was necessary for the mould to guarantee the high degree of coincidence for actual size and design value. Therefore, surface accuracy control of large wind turbine blade mould was studied.
