| Abstract: | In this paper, we'll discuss how to set up a windmilltower similarity modal and transform a recorded strong instantaneouswind speed in to a model of air current corresponding to similar con-ditions.The analogue windage vibration test of the model tower and itsphotoelastic experiment under the dead load of wind are performed th-rough a vibration exciter.The job finished above represents a comple-te modelling method of windage structural vibration test. |
