In the second part the results of the experiments with mass damper, called Stockbridge damper, and its efficiency are presented. Stockbridge dampers effectively reduce vibrations by absorbing the energy supplied from the outside. In the real cases the power input comes from the wind. The efficiency of vibration damping is analyzed in the frequency domain corresponding to aeolian frequencies. Two-mass dampers were analyzed and their dynamic characteristics were presented and described by the power function in the frequency domain. The additional parameter - phase angle between excitation force and the velocity of the vibrating damper was presented as well.
