Lateral Rotor Vibration Analysis Model

摘要

In this article we examine the lateral vibrations in rotating machinery can lead to rotor unstable behaviour. In some types of rotating machinery, the angular speed is subjected to wide ranges of change. The problem is to find the range of angular speeds for which a machine exhibits stable behaviour in the presence of the coupling of dynamical modes. For determine of mathematical model for vibration we will use F?ppl-Jeffcott rotor model. We will examine a undamped and damped vibration on the F?ppl-Jeffcott rotor model.
