Stability and Stationary Response of a Skew Jeffcott Rotor With Geometric Uncertainty
TL;DR: In this article, the dynamical behavior of an asymmetrical Jeffcott rotor subjected to a base translational motion is investigated and the stability is first studied by introducing a transformation of coordinates (feasible in this case) making the problem simpler.

Resonance analysis of gyroscopic nonlinear spinning shafts with parametric excitations and speed fluctuations
Majid Shahgholi,S.E. Khadem +1 more
TL;DR: In this article, simultaneous primary resonances due to imbalance periodic force and parametric resonance due to two sources of parametric excitations for a simply supported nonlinear spinning shaft with unequal mass moments of inertia and flexural rigidities in the direction of principal axes were investigated.
