Abstract :
This paper is devoted to the study of foundation effects on the dynamic characteristics of rotor-bearing systems. The modelling and analysis of rotor-bearing–foundation systems based on the finite element method are discussed. A substructure procedure which includes the foundation effects in the motion equations and the application of the dynamic solver of a commercial package is addressed. The design criteria of the foundation for rotating machinery avoiding resonance and suppressing response have also been emphasized through numerical examples.
