题目：小型风力发电机叶片设计与制造的研究 ; The study of the small wind turbine blade design and manufacture ABSTRACT With the consumption of fossil fuels and their serious impact on the environment, the wind energy with the advantages of clean and can be recycled for use is growing importance to many countries and they are actively developing and utilizing its wind resource, China is no exception.; The main results achieved are as following: 1. According to the classic theory of the wind turbine blade design and using 3D modeling software, the blade’s 3-D solid model is established. According to the situation that there are lots of aerofoil data, a suitable modeling method is put out which make the modeling more quickly and accurately. 2. Based on the solid model and aerofoil design section respectively, two blade mold design and manufacturing methods are put out. There are different advantages in each of two methods, which can be chosen according to the actual production conditions.;3. In order to create high-strength lightweight blade, the key technology of composite material manufacture are analysised and the relevant parameters are identified. Using of strain measurement technology, composite material’s strength properties and the constants are determined. It provide material’s data for FEM analysis . 4. Introduced the manufacturing process of how complete the blade. At last, we take the static and vibration experiments to blade; the result verified the correctness of finite element analysis and the blade’s practicality .; Background and Significance At present, the world attach great importance to energy issues, as the total energy consumption of the first electricity is a secondary energy by other energy converted from.The world energy production is mainly by the constraints of the natural environment by hydropower and thermal power, Hydropower is restricted by the constrai
