| As the over consumption of primary energy and environmental pollution is more and more serious, wind energy is paid more and more attention, and become a hot spot of research and development. Wind energy is a kind of new energy, and unit equipment is very important. With the continuous development of wind generation technology and the increasing of single wind-driven generator power, the complicacy of its mechanical features is also increased. Therefore, the analysis of the static and dynamic characteristics of wind turbine is particularly important.The program focuses on the researches of H-type vertical axis wind turbine, and analyzes the static and dynamic characteristics of wind turbine, main work is as follows:(1)It reviews the research background of this program, introduces the existing research methods and research achievements of the vertical axis wind turbine, expatiates the finite element analysis method and ANSYS software, and gives the structure optimization scheme of the wind turbine.(2) Analyses the static characteristics of the main structures of the wind turbine, such as the spindle, blades arm, blade and tower statics. First, the stress status is analyzed, and then the static analysis of these main structures is made to discuss the strength and stiffness of the structures. In the process of the blade loading, the FLUENT is used to calculate the wind pressure value of the blade, and the method how to get wind pressure and load on the ANSYS by the function is expatiated, the function is got from the EXCEL and the MATLAB. The method can provide an idea for the accurate calculation of wind pressure. The Pro/Engineer is used to set up the finite element model of the blade.(3)The dynamic characteristics of the main structures of the wind turbine are analyzed, and the vibration frequency is got. These structures are verified won’t happen resonance. The cloud pictures of the vertical axis wind turbine are discussed, and the reference for the next step design is provided. |
