Abstract |
In various industrial applications there is a need for higher speed, yet
reliably operating rotating machinery. A key factor in achieving this type
of machinery continues to be the ability to accurately predict the dynamic
response and stability of a rotor-bearing system.
This thesis introduces and explains the nature of rotor dynamic
phenomena from comparatively simple analytic models. Starting with the
most simple rotor model that is supported in two rigid bearings at its
ends, the more realistic and more involved cases are considered by
incorporating the effects of flexible bearings. Knowledge of these
phenomena is fundamental to an understanding of the behavior of
complex models, which corresponds to the real model of turbo machines
namely turbocharger, and determine the dynamic characteristics for it which is very important in its design. |
