Vibration control analysis of active tuned mass damper for large span buildings under simple spectrum excitation

Abstract

Aiming at the defect that the traditional damper has little anti-vibration control effect, an active frequency-modulated mass damper anti-vibration control method for large-span buildings under simple spectrum excitation was proposed. The anti-vibration matrix of active Tuned mass damper was established, the vibration vector displacement was calculated, the matrix transformation expression was designed, the vibration response value was calculated, the effect of vibration response on anti-vibration displacement was analyzed, then the stability and coordination control of active tuned mass damper were realized. A comparative experiment was presented to verify that the proposed method could increase the amplitude of anti-vibration control of the damper in the application.
