In rotor dynamics, a traditional way of representing the dynamics of hydrodynamic bearings is using stiffness/damping coefficients. It is thus necessary to carry out a linearization of hydrodynamic forces around the shaft’s equilibrium position. Ho

Bifurcations and limit cycle prediction of rotor systems with fluid-film bearings using Spectral Submanifolds

Autor: Arthur Guilherme Mereles, Diogo Stuani Alves, Katia Lucchesi Cavalca

Many rotating machines utilize a fluid type bearing. Despite their reliability and high load capacity, these bearings often show instabilities due to the interaction between the fluid media and the rotating shaft. These instabilities, known as oil-wh

Fault identification is a recurrent topic in rotating machines field. The evaluation of fault parameters allows better maintenance of such expensive and, sometimes, large machines. Unbalance is one of the most common faults, and it is inherent to rot
