This chapter presented a method of analyzing general multiple rigid-body systems interconnected by

linear springs and linear dampers. The mathematical modeling was presented for small vibrations

where nonlinear geometry effects and gyroscopic couplings were negligible and the deflection

characteristics of the mountings were linear. There is a shortage of published material on general

mathematical modeling of flexibly supported rigid multibody systems for vibration analysis. Detailed

mathematics of time domain, frequency domain and eigenvalue/eigenvector analyses can be found in

standard vibration textbooks. Some are listed in the references section, but this list is not exhaustive.

This chapter also gives a precise and clear formulation suitable for computational implementation.

The formulation presented in this chapter forms the core of the vibration analysis suite “VIBRATIO”,

a version of which is made available to the users of this handbook, at www.signal-research.com, as

indicated in the text.
