“…It is possible to observe from the graph that both the load and the stability limit curves varied for each of the simulated objects. This is in accordance with the literature [21], [22], because for the model analyzed, the density influences both the load curve and the stability limit curve. But the Young's modulus influences only the stability limit curve.…”

“…It is also observed that, although the assignment of values to the parameters happens at random, it follows the mechanisms of probability of occurrence. It is important to note that these mechanisms represent the uncertainties associated with the parameters through probabilistic functions [17]- [19], [21], [22].…”

“…Lateral vibration of the rotating shafts is an unwanted phenomenon that affects the efficiency and performance of the rotating machines. Therefore, many control methodologies have been introduced to eliminate or at least mitigate this undesired phenomenon [26][27][28][29][30][31][32][33][34][35][36][37][38]. Ishida and Inoue [26] introduced a linear dynamic absorber utilizing four electro-magnetic poles to control the lateral vibrations of a non-linear Jeffcott system.…”

“…They used the Jeffcott rotor with an offset disc, and developed an algorithm that allows the identification of the crack, as well as to estimate other model parameters, such as damping, unbalance, and constants due the supports. The study developed by Heindel et al [8] included active bearings in a Jeffcott rotor as well, proving their ability to eliminate bearing forces and resonance when the machine is subject to unbalance. Eissa and Saeed [9] studied a horizontally supported Jeffcott rotor system, proposing a controller for the nonlinear vibrations, which results into a reduction in oscillation amplitude.…”
