Aspects Concerning the Dynamic Behavior of a Rotor-Foundation System
Journal Title: Romanian Journal of Acoustics and Vibration - Year 2011, Vol 8, Issue 2
Abstract
The paper analyses the coupled vibrations of a rotor-foundation system, when the domain of the critical angular velocity is perturbed, which can lead to the damage of the shaft, by vibration of the gear, as well as of the foundation. The phenomenon is studied by means of a two degree of freedom model, described by differential quations containing second-order terms. The analysis of the system starts from decoupled linear equations and continues by applying methods specific to the theory of the dynamic systems. The dynamic behavior is thus understood, while practical consequences can be drawn, regarding the optimal values of the parameters of the system.
