小型风力发电机叶片设计与制造的研究

摘要

The blade is a key component of the wind turbine. In order to produce a good GRP blade, studied the design of the small wind turbine blade and manufacture the mold. According to the wind energy resources in local,the design power of the wind turbine is 300W. First,design the basic size of the wind turbine. Select NACA4412 airfoil model,through calculation and analysis , determine the blade airfoil profile and the specific size. Then, using the CAD and CAM technology, designed a set of the small wind turbine GRP blades and produced the mold. To laid a good foundation in achieving large-scale production of the wind turbine GRP blade.%叶片是风力发电机(简称风机)的关键部件,为了制造出优良的小型风机叶片,对小型风机叶片的设计、材料的选择以及模具制造进行了研究.根据当地风能资源的情况,风机的设计功率为300W.首先设计出风轮的基本尺寸,选择NACA4412翼型,经过计算和分析,确定叶片剖面翼型和具体尺寸；其次根据风机叶片的受力情况及其他要求,选择玻璃纤维增强复合材料制作叶片；然后运用CAD和CAM技术,设计了一套小型风机玻璃钢复合材料的叶片并制作了模具.为风机玻璃钢叶片进一步实现规模化生产奠定了良好的基础.
