Abstract:
A theoretical approach was developed and programmed to analyze dynamic response of turbomachinery frame foundations supported by piles or a foundation slab. The study investigates interaction of all components of the system, i.e. flexible rotors, visco-elastic oil film, space frame, flexible mat, piles and soil. The effect of the foundation on vibration amplitudes of the frame and rotors is demonstrated.
