Modal Analysis of Horizontal Axis Wind Turbine Rotor Blade with Distinct Configurations under Aerodynamic Loading Cycle

Öz:
Q-Blade simulation tool was employed in modal analysis of horizontal axis wind turbine bladewith three distinct configurations (with spar, no spar and solid) to determine the configuration withadequate structural integrity under aerodynamic loading conditions. The blade configurations wereanalysed in four different modes based on the flapwise and edgewise response of the blade toaerodynamic loads/forces, and the corresponding modal eigenfrequencies were evaluated.Bending due to combined effects of flapwise and edgewise modal frequencies on the blade werealso evaluated at different rotor blade speeds ranging from 2-8m/s. It was observed that the solidblade configuration had the least modal eigenfrequencies for both flapwise and edgewise responsein all the four modes as follows: 22.03 and 62.60 Hz in mode 1, 58.0 and 212.8 Hz in mode 2,122.6 and 600.6 Hz in mode 3, 194.4 and 1118.9 Hz in mode 4. The rotor blade configuration withNo spar had the highest modal eigenfrequencies for both flapwise and edgewise response in all thefour modes followed by the blade configuration with spar. Bending of the rotor blade due tocombined effects of flapwise and edgewise modal frequencies at the aforementioned blade speedswere also highest in blade configuration with No spar and lowest in the solid blade configuration.The low modal eigenfrequencies and low bending values on the solid blade configuration implyhigh stiffness and strength but with additional mass, which is why 6000 series aluminium wasselected in order to minimize the extra weight.
