Two methods for calculating the power input to vibrating beams and plates excited by multiple discrete random forces are developed. The power input is expressed in terms of the cross-power spectral density between the exciting forces. An approximate energy density solution is obtained using energy f

Energy flow analysis (EFA) is an analytical tool for prediction of the frequency-averaged vibrational response of built-up structures at high audible frequencies. The procedure is based on two developments; first, the derivation of the partial differential equations that govern the propagation of en
In view of structure-borne sound, vibrational power #ow analysis is investigated for damaged beam structures. In this paper, the damage is modelled as a joint of a local spring. The damage point transfer matrix and the beam element transfer matrix are deduced, then the relations of the vibrational p
