“…The change rule is fundamentally different to that of the linear model, which illustrates that the weak nonlinear stiffness can cause obvious nonlinear characteristics. In addition, the jump phenomenon occurs when the detuning parameter σ changes and the jump points do not overlap in the case of different changing orders; these results are consistent with those calculated by Eissa [30]. Figure 4a and Figure 4b show the effects of k s and ω 0 on analytic responses for different σ.…”

“…Amer and co-workers [17][18][19][20][21] studied a rotor-active magnetic bearing with quadratic and cubic non-linearities and the time-varying stiffness under harmonic and parametric excitations. The steady state solution of a rotor system is studied under different resonance cases applying a perturbation technique.…”

“…Since magnetic levitation does not use long reaching and joint parts, wear and maintenance problem caused by friction are completely eliminated. Magnetic levitation has been used in magnetic bearings [1][2][3][4][5], vibration suspension [6][7][8][9] and position tracking [10]. Furthermore, different types of control techniques have been used in magnetic levitation systems.…”
