Study the Structural Behavior of Turbo Generator Foundation Connected with Passive Supplemental Devices

Abstract

The study of the dynamic properties of Turbo-Generator foundation with and without using isolators and supplemental damping devices are considered in this thesis using both basic principles calculation method and finite element method. The high vibrations of machines especially Turbo-Generators machines leads to use massive masses of foundations to absorb the dynamic loads generated by machines. The work in this thesis investigates the effect of using isolators and passive supplemental damping devices in accommodate these big amount of dynamic loads, also investigates how it could lead to change the dynamic responses of Turbo-Generator foundations to be in the safe frequency range.
