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 the wind power industry, the wind turbine blades have evolved from the original kW level to the current 6MW level or even larger. Wind turbine blades have been using FRP composite materials, molding process using vacuum infusion molding. Mold length from the initial development of 10m to 60m now, even longer, the profile accuracy becomes more difficult to control. The efficiency of wind power directly depends on the accuracy of the blade wing shape, which requires blade mold profile size and design value has a high degree of coincidence. Therefore, this paper carried out a large-scale wind turbine blade mold surface precision control and other related research.
