Abstract

An alternate procedure for deriving a reduced-order model is presented. The Routh expansion method is used and preserves the original system impulse response energy. This procedure does not acquire knowledge of the system eigenvalues/eigenvectors and guarantees a stable reduced-order model if the original system is stable. The method is illustrated on a simply supported beam subjected to moment excitation. A comparison is made with reduced-order models obtained using other methods.
