System Prediction Using Damped Component Modes

This paper describes a method of predicting the vibrational characteristics of a system when the components, which have mass, stiffness and damping, are connected together by connections which are characterized by stiffness and damping. A matrix set involving the complex eigenvalues and eigenvectors of the components together with a connection matrix is solved to give system eigenvalues and eigenvectors. The application of this method to a particular system is shown to produce the same results as those obtained for the unsubstructured system.
