Abstract

Rotating machinery operating in non-inertial frames represents a research domain of high interest for the aeronautical, railroad and shipping industries. This paper investigates the variations of rotor frequencies, expressed by the Campbell diagrams, using two models. One model is analytical, providing closed form solutions and considering a rotor with four degrees of freedom. The second model is based on finite elements, Timoshenko beam formulation, for the same rotor. Campbell diagrams are obtained for both cases using computer codes developed by the first author. Good agreement between the models at the common eigenmodes, validate the more complex model.
