| Abstract: | This paper analyzes forces and moments acting on blades of the rotator of a wind turbine.It gives a dynamic model of the blades and deduces their pitching/torsional/swinging vibration equations as well as corresponding first-order natural vibration frequencies.It also discusses effects of relevant parameters on the natural vibration frequencies in the three directions.Thus it provides a dynamic basis for calculation for wind turbine blade designs. |
