Energetics of In-plane Motions in Coupled Plate Structures

open access: yes한국해양공학회지, 2020
Energy flow analysis (EFA) has been used to predict the frequency-averaged vibrational responses of built-up structures at high frequencies. In this study, the frequency-averaged exact energetics of the in-plane motions of the plate were derived for the ...

Prediction of interior noise in rolling stock by statistical energy analysis

open access: yesNihon Kikai Gakkai ronbunshu, 2015
A model of statistical energy analysis (SEA) of railway carbodies was developed to predict interior noise in rolling stock. Since the carbody shell is made of double skin structures of extruded aluminum and their coupling loss factors (CLFs) cannot be ...
