Analysis the Influence of Double Forked Intelligent Blade Tip Structure on Vibration Mode of Wind Turbine under Yaw by Big Data Technology

In order to study the influence of double forked intelligent blade tip structure on natural frequency and vibration frequency of wind turbine at different yaw angles, numerical simulation of wind turbine with different blade tip structure was carried out by using big data technology and ANSYS software. The numerical results show that: under different yaw angles and the same wind turbine speed, the double forked blade tip structure can slightly reduce the first and second order mode, which are less than 1Hz. Under different wind turbine speeds and the same yaw angle, the double forked blade tip can significantly improve the vibration frequency, with the first order vibration frequency dropping up to 11.96% and the second order vibration frequency dropping up to 6.8%. It can be seen that the results provide experimental basis for vibration characteristics of wind turbine under yaw condition.
