VIBRATION TEST USING A PLATE MODEL TO VERIFY THE EFFECT OF VIBRATION CONTROL OF TUNED MASS DAMPERS WITH INITIAL DISPLACEMENT UNDER IMPULSE LOADING

Abstract

To effectively control transient responses, we propose TMDs with initial displacement. The initial displacement can change the phases of beat envelope curves resulting from superposition of two vibration modes with closely spaced natural frequencies. In this paper, we describe the vibration test under impulse loading to verify the effect of the proposed system experimentally and that a model of TMD made on an experimental basis works validly. Firstly, we explain the effect of vibration control of the proposed method to the plate model on the analytical basis. Then, we explain experimental results and lastly compared experimental results and analytical results.
