Influence of plain journal bearing parameters on the rotor nonlinear behaviour
Original language description
This paper deals with the investigation of the rotor nonlinear behaviour with respect to design parameters of plain journal bearings. The Reynolds equation is solved numerically employing a verified in-house solver based on finite differences. A pressure distribution serves for the calculation of nonlinear bearing forces acting on the rotor. Bearing forces together with the model of a rotating structure form equations of motion of the whole system as a set of ordinary differential equations. The nonlinear rotor behaviour is solved using direct numerical integration of equations of motion, which is a suitable way for the evaluation of possible instabilities with respect to bearing parameters. Obtained numerical results are compared with results calculated using a commercial simulation software.
