| Özet |
| In this work, the free vibration analysis is done on a blade of AIR X-400W horizontal axis wind turbine. Turbine blade length is designed as 66.5 cm and 4140 steel, shape memory alloys (Ni-Ti, Cu-Zn-Al and Cu-Al-Ni) are used in blade root connection. In this project vibration analysis has been used to determine the natural frequencies and the mode shapes of wind turbine blades for each materials. The total deformation in the wind blade are determined using the finite element method with ANSYS in which the skin and the core of the blade are modeled using solid elements, respectively. The rotor that blades are connected is rotating 400 rpm in 8m/s wind speed. Accordingly, resonance frequencies will be occurred were determined for each materials. As a result of the analysis; the maximum total deformation was observed in 5. mode of natural frequency that blade root connection is Cu-Zn-Al. Generally total deformation values appeared close to each other. The performance of blade was evaluated for each materials were used in blade root connection. |
