Vibration Analysis by Modal Energy Analysis Method. 1st Report, Proposition of Modal Energy Analysis Method.

Abstract

The authors propose and develop a new experimental vibration analysis method named modal energy analysis method in this study. Is this first report, the modal energy analysis method is proposed and its basic theory is explained. By using the proposed method, the individual loss factors of all components can be identified practically at any vibratory frequency, in the vicinity of resonant frequences, from experimentally measured FRFs of objective total structures. Two simulative and an actual experimentally based applications are carried out and their results are shown in order to verify the theory.
