transient dynamics of rigid rotor and elastic (Jeffcott) rotor in linear elastic bearings and journal bearings (analytical short bearing solution).
ODEs of the rotors are taken from my Ph.D. dissertation: Nowald, Gerrit Edgar (2018). Numerical Investigation of Rotors in Floating Ring Bearings using Co-Simulation. Technische Universität Darmstadt. https://tuprints.ulb.tu-darmstadt.de/8186
Short bearing theory is taken from Vrande, van de, B. L. (2001). Nonlinear dynamics of elementary rotor systems with compliant plain journal bearings. Technische Universiteit Eindhoven. https://doi.org/10.6100/IR550147
