Abstract
In this study, the effect of support
stiffness on the dynamic behaviour of a large industrial rotor is studied using
simulation models and experimental test setup having a mechanical apparatus for changing the horizontal support stiffness. Two
different simulation models with different levels of complexity were created to
simulate the behaviour of the system. Such verified simulation models can be used to predict the critical
speeds and minimum vibration operating speed areas. The
achievements of this paper could be utilized in the industries using large
rotors when operating conditions can be taken into consideration already in
rotor system development.
