✦ Synopsis

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 flow analysis. The power input calculations and the energy density response predictions are verified using modal analysis for different coherence conditions between the random excitation forces.
