Nowadays, rotating machines tend to operate at high speeds and sometimes, in complex situations such as on moving support. Thus, accurate prediction of their dynamic behavior must be made to ensure a reliable design. In this paper a finite element model is developed, to simulate the dynamic behavior of a flexible rotor with constant/variable spin speed, supported by a rigid base undergoing a general movement. Simulation results are presented and discussed for different cases of base movements and running speed variations.
Key words: Rotordynamics / base motion / variable spin speed / finite element method / simulation
