Stability of Rotor-Bearing Systems (original) (raw)

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 paper introduces and explains the nature of rotordynamic 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 rotors of turbomachines. ROTOR-YATAK SİSTEMLERİNİN KARARLILIĞI ÖZET Endüstrideki çeşitli uygulamalarda yüksek hızının yanısıra güvenli olarak çalışan dönen rotorlu makinaya ihtiyaç vardır. Bu tür bir makinayı elde etmedeki anahtar faktörün rotor-yatak sisteminin dinamik tepki...
