The Structural Design And Static Analysis Of Ring-shaped Wind Wheel

In order to reduce the fan speed and increase wind energy utilization start, bold ideas put forward a new structure of the wind wheel-shaped ring wind wheel. By Ye Glauert prime theory and theoretical research, come to wind round shaped ring theoretical feasibility; comparative analysis of various airfoil aerodynamic performance differences in the identified ring shaped wind round airfoil with NACA series; In addition, the analysis of the wind wheel diameter size, the location of ring shaped starting respectively, wind speed and wind energy utilization coefficient, determined to adopt a ring shaped airfoil as the airfoil NACA23012 profile, such as the distorted cross-section ring structure, the design of the wind wheel diameter of 43 meters, position in the wind wheel diameter of 1/3, as well as Central and leaf shaped buckle then using the connection mode of riveting solid conclusions; and take advantage of PRO/E on the wind shaped ring launches and leaves of three-dimensional solid modeling, as well as a simple stress analysis, has been shaped junction of Central and leaves the greatest stress, and increased the fan shaped ring can withstand extreme wind speed decreased, reaching only 45 m/s.
