| Abstract: | A magic wind-wheel phenomenon is introduced. According to a new established physical model related to the phenomenon, the mathematical derivation has been given: the motion of the wind-wheel bar is a two dimension forced vibration, with a elliptical motion trace of the bar end, the vibration can be resolved into two orthogonal vibrations, owing to the phase difference between two vibrations, rotation orientations of elliptical motions of the bar end are difference, which results in variation of rotation orientations of wind-wheel blades. Finally, the experimental results are given. |
