The required parameters to simulate the model were obtained from the actual prototype. Rigid rotor dynamics, including the gyroscopic effects and rotor imbalances were incorporated within Bond-Graph modeling approaches. Available experimental results were used for validation. This encompasses the Campbell-diagram, the mean displacement and the amplitude responses at different rotational speed.
