| Abstract: | In this paper, we'll discuss how to set up a windmill tower similarity model and transform a recorded strong instantanceus wind speed into a model of air current corresponding to similar conditions The analogue windage vibration test of the model tower and its photo-elastic experiment under the dead load of wind are performed through a vibration exciter. The finished job above represents a complete modelling method of windage structural vibration test. |
