Abstract
The results of the study of vibration sensitivity of a rotor of stationary gas-turbine unit (GTU) on slide bearings to the change of the main settings of the system are described in the paper. The authors used a beam model of the rotor which takes into account the non-linear stiffness and damping characteristics of an oil film in radial bearings, and a multi-disciplinary model of rotor dynamics including the model of the shaft, rotating discs and radial bearings. Numerical calculations for calculating the orbits of GTU rotor at different operating conditions are performed. The paper also demonstrates the sensitivity of the “rotor-bearing” system to a change of system parameters such as a disbalance of the rotor, constructive damping and viscosity of the oil in bearings.
